Novel composition of equalizer combined with adaptive antenna array

摘要

This paper proposes a novel equalizer using the MINT on DS-CDMA with adaptive antenna array. The method to introduce interference cancellers and equalizers into the DS-CDMA system with adaptive antenna array has been already proposed in order to improve the BER performance. However, if channel characteristic of a user is nonminimum phase, the equalizers in the method cannot realize exact inverse filtering. To solve this problem, we apply the MINT, which can realize exact inverse filtering by using multiple inputs, to the conventional method. Simulation results demonstrate that the proposed method can realize higher BER performance than the conventional one.
