American National Standards Institute

The American National Standards Institute (ANSI) is a private nonprofit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States.

See CdmaOne and American National Standards Institute

Autocorrelation

Autocorrelation, sometimes known as serial correlation in the discrete time case, is the correlation of a signal with a delayed copy of itself as a function of delay.

See CdmaOne and Autocorrelation

Bit

The bit is the most basic unit of information in computing and digital communication.

See CdmaOne and Bit

CDMA spectral efficiency

CDMA spectral efficiency refers to the system spectral efficiency in bit/s/Hz/site or Erlang/MHz/site that can be achieved in a certain CDMA based wireless communication system.

See CdmaOne and CDMA spectral efficiency

CDMA2000

CDMA2000 (also known as C2K or IMT Multi‑Carrier (IMT‑MC)) is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites. CdmaOne and CDMA2000 are 3rd Generation Partnership Project 2 standards.

See CdmaOne and CDMA2000

Channel access method

In telecommunications and computer networks, a channel access method or multiple access method allows more than two terminals connected to the same transmission medium to transmit over it and to share its capacity.

See CdmaOne and Channel access method

Code-division multiple access

Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies.

See CdmaOne and Code-division multiple access

Comparison of mobile phone standards

This is a comparison of standards of wireless networking technologies for devices such as mobile phones.

See CdmaOne and Comparison of mobile phone standards

Digital AMPS

IS-54 and IS-136 are second-generation (2G) mobile phone systems, known as Digital AMPS (D-AMPS), and most often referred to as TDMA, are a further development of the North American 1G mobile system Advanced Mobile Phone System (AMPS).

See CdmaOne and Digital AMPS

Digital radio

Digital radio is the use of digital technology to transmit or receive across the radio spectrum.

See CdmaOne and Digital radio

Frequency-division multiplexing

In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal.

See CdmaOne and Frequency-division multiplexing

Global Positioning System

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force.

See CdmaOne and Global Positioning System

GSM

The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.

See CdmaOne and GSM

Hadamard code

The Hadamard code is an error-correcting code named after Jacques Hadamard that is used for error detection and correction when transmitting messages over very noisy or unreliable channels.

See CdmaOne and Hadamard code

Handover

In cellular telecommunications, handover, or handoff, is the process of transferring an ongoing call or data session from one channel connected to the core network to another channel.

See CdmaOne and Handover

Hutchison Asia Telecom Group

Hutchison Asia Telecom Group or HAT, is a division of Hong Kong-based multinational conglomerate CK Hutchison Holdings.

See CdmaOne and Hutchison Asia Telecom Group

Medium access control

In IEEE 802 LAN/MAN standards, the medium access control (MAC), also called media access control, is the layer that controls the hardware responsible for interaction with the wired (electrical or optical) or wireless transmission medium.

See CdmaOne and Medium access control

Mobile phone

A mobile phone or cell phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone (landline phone).

See CdmaOne and Mobile phone

Noisy-channel coding theorem

In information theory, the noisy-channel coding theorem (sometimes Shannon's theorem or Shannon's limit), establishes that for any given degree of noise contamination of a communication channel, it is possible (in theory) to communicate discrete data (digital information) nearly error-free up to a computable maximum rate through the channel.

See CdmaOne and Noisy-channel coding theorem

Phase-shift keying

Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency carrier wave.

See CdmaOne and Phase-shift keying

Physical layer

In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer: the layer most closely associated with the physical connection between devices.

See CdmaOne and Physical layer

Pseudorandom binary sequence

A pseudorandom binary sequence (PRBS), pseudorandom binary code or pseudorandom bitstream is a binary sequence that, while generated with a deterministic algorithm, is difficult to predict and exhibits statistical behavior similar to a truly random sequence.

See CdmaOne and Pseudorandom binary sequence

Pseudorandom noise

In cryptography, pseudorandom noise (PRN) is a signal similar to noise which satisfies one or more of the standard tests for statistical randomness.

See CdmaOne and Pseudorandom noise

Qualcomm

Qualcomm Incorporated is an American multinational corporation headquartered in San Diego, California, and incorporated in Delaware.

See CdmaOne and Qualcomm

Rake receiver

A rake receiver is a radio receiver designed to counter the effects of multipath fading.

See CdmaOne and Rake receiver

Soft handover

Soft handover or soft handoff refers to a feature used by the CDMA and W-CDMA standards, where a cell phone is simultaneously connected to two or more cells (or cell sectors) during a call.

See CdmaOne and Soft handover

Telecommunications Industry Association

The Telecommunications Industry Association (TIA) is accredited by the American National Standards Institute (ANSI) to develop voluntary, consensus-based industry standards for a wide variety of information and communication technology (ICT) products, and currently represents nearly 400 companies.

See CdmaOne and Telecommunications Industry Association

Telephone

A telephone, colloquially referred to as a phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly.

See CdmaOne and Telephone

Time-division multiple access

Time-division multiple access (TDMA) is a channel access method for shared-medium networks.

See CdmaOne and Time-division multiple access

Viterbi decoder

A Viterbi decoder uses the Viterbi algorithm for decoding a bitstream that has been encoded using a convolutional code or trellis code.

See CdmaOne and Viterbi decoder

2G

2G is a short notation for second-generation cellular network, a group of technology standards employed for cellular networks.

See CdmaOne and 2G
