Performance Analysis of a Hybrid DS/SFH CDMA System Using Analytical and Measured Pico Cellular Chan - Selected Areas in Communications, IEEE Journal on

This paper presents the throughput and delay analysis of a packet-switched code division multiple access (CDMA) network based on the hybrid direct sequence (DS)/slow frequency hopping (SFH) spread-spectrum multiple access (SS MA) technique with Q-, B-, and D-PSK modulation using analytical and measured pic0 cellular channels. The performance of the hybrid DSISFH, DS, and SFH multiple access techniques have been compared in a pic0 cellular personal communications network (PCN) environment. Multipath and multiple access interference are considered. The performance is evaluated for a given delay spread and a fixed bandwidth. The effects of forward error correction (FEC) coding and diversity techniques, such as selection diversity and maximal ratio combining on the performance, are also investigated.
