Description/Abstract
When transmitting 32kbit/s adaptive differential pulse(ADPCM) speech using Reed-Solomon error correction coding and 16 level quadrature amplitude modulation(16-QAM), our 20 slot packet reservation multiple access(PRMA) assisted cordless telecommunications(CT) scheme supported 36-38 speech users with negligible objective and subjective speech degradation. The average number of users per slot was nearly doubled due to deploying PRMA and toll quality speech was transmitted in a user bandwidth ~11.6kHz. For a channel signal-to-noise(SNR) in excess of 25dB, a Rayleigh fading channel and mobile speeds above 2mph the speech segmental SNR degradation was less than 0.3dB.
