Abstract

For the next generation mobile systems, the design of high speed reliable wireless communications supporting data, image and voice transmission is of primary interest. Current cellular DS-CDMA systems have been designed to operate at low- or medium-bit rate transmission, of 9.6 or 14.4 kbits/s, but proposals to increase this data rate to 64 kbits/s, 384 kbits/s and 2 Mbits/s are currently being evaluated by the standard committees such as the Universal Mobile Telecommunications Service (UMTS or IMT-2000). We investigate the performance achievable by an asynchronous DS-CDMA system operating at data rates of up to 8 Mbits/s in conjunction with either QPSK or 16-QAM modulation and space-path diversity techniques in a frequency selective channel.
