Effect of capture models on the performance of the CDPA cellular architecture

In this paper we present the performance of the capture division packet access (CDPA) cellular architecture obtained by using a more accurate packet capture model than the one used in previously appeared analyses. In the new model, the effect of cocell interference is evaluated on each bit of the packet. The results obtained with this new model are directly related to the propagation parameters that are normally used in the literature on cellular systems, such as the exponent of the near-far power attenuation law. In practice, we find that CDPA can achieve better performance than that predicted by the “threshold” model used previously. With this new model we also evaluate the effect of forward error correcting techniques, which are found to provide only a small improvement in the maximum throughput
