“…Generally, the greater the number of slots, the greater the advantage of PRMA over non-PRMA systems, since the statistical multiplexing gain approaches the reciprocal of the speech activity ratio. Furthermore, PRMA-assisted adaptive modulation achieves an additional 80% capacity increase over PRMA-assisted binary modulation [340]. The speech performance of our adaptive system evaluated in terms of SEGSNR and CD is unimpaired by channel effects for SNR values in excess of about 8, 10, and 20 dB when using diversity-assisted DPSK, DQPSK, and 16-StQAM, respectively, although in dispersive environments, a reduced performance is expected.…”

“…Nevertheless, it is always possible to plot the number of channels to be reserved against the probability of channel occupancy for the PU. 3 Similar ideas for reservations have been suggested in the time domain in [15] as packet reservation multi-access. Complete sharing, complete partitioning and virtual partitioning have also been suggested for multi-access [16].…”

“…The operation of PRMA is based on the speech activity detector SAD being able to reliably detect idle speech segments. Inactive users' time slots are allocated to other users, who become active [10]. The voice traffic model used here is assumed to be slow SAD, which responds only to the principle talkspurts and gaps, with typical mean values of 1 sec and 1.35 sec respectively [6].…”
