Abstract :
Broadcast transmission is used in the downlink of TD SCDMA trunking systems with the same frequency and same time slot macro-diversity model, and base stations transmit the same signal simultaneously. Signal that target user receives from neighbor cells is useful instead of interference, which can strengthen the useful signal and lower the interference. Motivated by this fact, we discuss three types of receivers in this paper. They are matched-filter receiver, receiver with method 1 (with perfect channel estimation), receiver with method 2 (linear combination). Moreover, the system performance of the above receivers in three typical scenarios is simulated and analyzed.
