Research on TD-SCDMA System Based on Joint Detection and Smart Antenna Technology

Abstract:

Article Preview

Channel estimation of TD-SCDMA is inaccurate if Joint Detection is separately used in anti-interference progress, and when the number of users or channels increases, amount of calculation is large, real-time control is hard to implement too; if Smart Antenna is only adopted, the formed beam which points to the user is likely to interfere other users. Especially for high-speed mobile users, beam forming bias exists. To solve this problem, combination of Joint Detection and Smart Antenna is proposed in the paper. Simulation results show that the combination not only improves capacity of system remarkably but also eliminate the multiple access interference (MAI)
