Paper Abstract

Time-varying multipath fading associated with the wireless link limit the capacity of a wireless system. To adapt to this adverse radio environment efficiently, we investigate the use of a pilot-aided fade-resistant transmission scheme for the uplink of a chip-interleaved code division multiple access (CDMA) system. We analyze the trade-off between the number of diversity branches and the channel estimation error. We derive the optimum ratio of pilot signal power to information signal power. Our numerical study indicates that depending on the transmitter power and channel condition, the proposed system is capable of outperforming the conventional CDMA system.
