| Abstract(in English) | 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, 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 or the 4-phase signal de-sign without co-channel interference for approximately synchronized uplink in cellular CDMA systems. Farthermore, using Gold-like sequences as the basic sequences, we can design 2-phase signal of high information transmission rate without co-channel interference for approximately synchronized CDMA systems. |
