摘要：
Power control or interference cancellation requires heavy cost for uplink in mobile CDMA systems. So Suehiro proposed 2-phase or 4-phase signal design for approximately synchronized CDMA systems without co-channel interference. In this paper, we show the validity of this method by designing binary M-ary CDMA signals without co-channel interference for approximately synchronized cellular mobile communication by using Gold-Like sequences as "the basic sequences." Farthermore, the carrier-frequency shift and the multipath properties are simulated. When the carrier frequencies are about 2000 MHz, the signals works almost without co-channel interference under the carrier-frequency shift of 2 kHz. This result of simulation shows us the usefulness of the 2-phase M-ary signal design without co-channel interference for approximately synchronized uplink in cellular CDMA systems.
