Performance of PRMA Schemes via Fading Channels

Hanzo, L, Cheung, J C S, Steele, R and Webb, W T (1993) Performance of PRMA Schemes via Fading Channels At VTC'93, United States. 18 - 20 May 1993. , pp. 913-916.

Record type: Conference or Workshop Item (Paper)


A packet reservation multiple access (PRMA) assisted microcellular cordless telecommunications (CT) system is investigated for office type environments. The objective speech quality is found as a function of channel signal to noise ratio (SNR) for transmission over narrowband Rayleigh fading channels, parameterised with the number of PRMA users. A moderate complexity 16-ary CT scheme consitituted by a 4 bit/symbol 32kbps adaptive differential pulse code modulation (ADPCM) speech codec, Reed-Solomon forward error correction (FEC) codec and diversity-assisted 16-level star quadrature amplitude modulation (16-StQAM) modem is proposed. The 264kBd 20-slot PRMA scheme supports 36 users while maintaining virtually imperceptible speech degradation for channel SNRs in excess of about 25dB and for mobile speeds above 2mph.
