Abstract: The Joint Detection technology is one part of the key technologies in the TD SCDMA system. In this paper, CDMA system model is introduced, then the Joint Detection and its implementation with field programmable gate array (FPGA) and digital signal processor(DSP) based on zero forcing block linear equalizer (ZF BLE) are analyzed, with which the multiple access interference(MAI) and intersymbol interference(ISI) are mitigated, thus reducing the whole system's bit error rate(BER), enhancing the communication quality and capacity prominently.
