An interleaver scheme for TD-SCDMA compatible GEO satellite communication system

A three-layer interleaver scheme, which is added into TD-SCDMA specification for the compatibility with satellite environment, is proposed for 3G mobile satellite communication systems. Simulation results for satellite channel are presented, which demonstrate that the third interleaver can improve the system performance significantly and satisfy the demands. The proposed interleaver design also provides the theory basis for researching upper layer protocol and transplanting TD-SCDMA specification to satellite environment.
