Glossary

8PSK

eight phase shift keying

16QAM

16 quadrature amplitude modulation

32QAM

32 quadrature amplitude modulation

ALC

automatic leveling control

AN

Access network. The network equipment providing data connectivity between a packet switched data network and the access terminals. An access network is equivalent to a base station.

API

application programming interface

Arb

arbitrary, as in arbitrary waveform

ASCII

American standard code for information interchange

AT

Access terminal. A device providing data connectivity to a user. An access terminal may be connected to a computing device such as a laptop personal computer or it may be a self-contained data device such as a personal digital assistant. An access terminal is equivalent to a mobile station. 

AWGN

additive white Gaussian noise

BBG

baseband generator

BER

bit error rate

BS

base station

BTTI

basic transmission time interval

Burst

a specifically structured set of data bits that occupies a single timeslot in a TDMA frame. In GSM there are four types of bursts: normal, frequency correction, synchronous, and access.

CCDF

complementary cumulative distribution function

CCITT

Comité Consultatif International Téléphonique et Télégraphique

Channel

set of channels transmitted between the access network and the access terminals within a given frequency assignment.

Continuous Pattern

The signal generator transmits a continuous data stream without framing or bursting.

Continuous PN9 Sequence

A non-truncated PN9 sequence where all 511 bits are transmitted before the sequence repeats.
