Abstract :
We provide a performance comparisons between the capture division packet access (CDPA), a novel cellular packet-access architecture, and more classic systems based on the FDMA/TDMA scheme. The CDPA is a single-frequency interference-limited system in which the packet access scheme is integrated with the interference protection scheme, being the protection attained through packet retransmission and time diversity. The comparison is obtained by simulating the operation of the two schemes in a real cellular environment in which co-channel interference, propagation and receiver structure are taken into account, The FDMA/TDMA scheme assumes that a suitable frequency reuse plan and forward error correction with perfect interleaving are used. Results show that CDPA provides considerably higher throughput than FDMA/TDMA in all propagation conditions. It is also shown that the CDPA throughput can be delivered within the delay and the packet-dropping probability constraints usually requested for real-time applications
