【Abstract】 With a view to the constructing and developing of future telecommunication networks, aimed at the problems about the theory, technology and application of radio access. this paper presents a packet synchronous CDMA (PSCDMA) radio transmit technology (RTT) which has the backward compatibility. The features of P-SCDMA and its important role in the future telecommunication systems are expatiated on. The various key technologies that should be thoroughly researched involved in the P-SCDMA are analyzed and discussed roundly.更多还原
