A Low-Rate Voice/Video Personal Communicator Scheme

Hanzo, L, Streit, J, Salami, R and Webb, W (1995) A Low-Rate Voice/Video Personal Communicator Scheme At of the IEE RRAS'95, United Kingdom. 26 - 28 Sep 1995. , pp. 11-16.

Record type: Conference or Workshop Item (Other)


A personal communication system (PCS) transceiver is proposed and investigated. A 4.8 kbit/s transformed binary pulse excited (TBPE) linear predictive speech codec, source sensitivity matched Bose-Chaudhuri-Hocquenghem (BCH) block error correction codecs, non-coherent differentially coded non-coherent 16-level quadrature amplitude modulation (16-QAM) modem and packet reservation multiple access (PRMA) are deployed. The 2.15 kBd transceiver necessitates a signal-to-noise ratio (SNR) and signal-to-interference ratio (SIR) in excess of about 24dB over Rayleigh0-fading channels in order to support 10-11 nearly un-impaired voice conversations within a bandwidth of 20kHz. Additionally, by reserving two PRMA time slots for video telephony, an 8.52 kbps videophone user can also be supported.
