In this paper, we analyze two kinds of joint detection algorithms ZF-BLE and MMSE-BLE. In theory, we compare their performance by computation and the ability of resisting ISI and MAI. Also, given different channel-impulse responses, various noise covariance matrix, single or smart antennas, we simulate their performance in up-link and down-link. Then we achieve conclusion that MMSE-BLE is better than ZF-BLE.
