Integrated voice-data transmission in CDMA packet PCNs

摘要

We present a new multiple access protocol based on DS-CDMA and slotted Aloha random access protocol with reservation for integrated voice-data transmission for packet personal communication networks (PCN). Voice terminals are assigned a code which they relinquish during their silence periods to be used by the data terminals. The data terminals contend for the codes using a reservation slotted Aloha protocol. We analyze the performance of the protocol incorporating the multiple access effects as well as the self interference associated with DS-CDMA systems.
