Joint detection can eliminate the inter-symbol interference which is caused by Multipath propagation, and multiple access interference which is caused by non-orthogonal multiplexing. In multipath fading channels, the error of channel estimation is inevitable. It will propagate to system matrix. In this dissertation, we utilize the joint detection to analyze the effect of channel estimation error Considering the error of system matrix and noise. We present the total least squares (TLS) way that can be used to overcome the defect of Zero Forcing Block Linear Equalizer (ZF-BLE). The emulated data have turned out that our proposed receiver is superior than the conventional ZF-BLE method.
