Description/Abstract
A personal communication system (PCS) transceiver is proposed and investigated. A 4.8 kbitls transformed binary pulse excited (TBPE) linear predictive speech codec, embedded source sensitivity-matched binary Bose-Chaudhuri-Hocquenghem (BCH) block error correction codecs, non-coherent differentially coded 16-level quadrature amplitude modulation (16-QAM) modem and packet reservation multiple access (PRUA) are deployed. The 2.15 kBd transceiver requires a signal-to-noise ratio (SNR) and signal-to-interference ratio (SIR) in excess of about 24 dB over Rayleigh-fading channels in order to support 1&11 nearly un-impaired voice conversations within a bandwidth of 30 kHz. Additionally, by reserving two PRMA time slots for video telephony, an 8.52 kbps videophone user can also be supported. Key words: Wireless multimedia communications, mobile voice and video telephony, transformed binary pulse excited speech coding, multilevel modulation, packet reservation multiple access, the Pan-American IS-54 mobile system.
