Abstract :
The effects of different speech source rates and various number of modulation levels on packet reservation multiple access (PRMA) efficiency in an adaptive transceiver are investigated under the constraint of fixed channel bandwidth and benign cochannel interference in office type cordless telecommunications (CT) environments. The number of PRMA users supported in a 200 kHz frequency slot ranges from 17 to 103, the required user bandwidth is between 11.8 and 1.94 kHz, and the number of PRMA users per slot is between 1.7 and 1.94, respectively.
