The research of multiuser detection in the TD-SCDMA trunking system

In TD-SCDMA system, multiuser detection technology is an effective measure for interference suppression. Because TD-SCDMA trunking system share the downlink resource in transmission and give priority to the radio emission way, so how to reduce the intercell interference effectively and improve system capacity become the main problems need to be solved in TD-SCDMA trunking system. This paper aims to research the suitable multiuser detection algorithms for TD-SCDMA trunking system, thus the system capacity and stability can be improved.
