Abstract

In this paper, two MAC schemes are defined and studied for DS-CDMA personal communication networks (PCN), namely preamble signaling access (PSA) and mini-slot signaling access (MSA). PSA uses preamble-packet slot structure while MSA is applying mini-slot techniques to solve the problems of code assignment and MAI control. Markovian chain models have been developed to analyze the performance of these two protocols for voice-only systems as well as data-only systems. The analytical model is shown to be very close to simulation results. Based on the results obtained from the analysis, it is shown that, for many cases, the MSA protocol performs better than the PSA protocol, especially for voice services
