Single-carrier frequency domain equalization with joint MMSE and PIC in DS-CDMA
Xin Qi · Modern Electronics Technique · 2013
The single-carrier overlap-cut frequency-domain equalization(OC-FDE) proposed recently requires no GI(Guard interval) inserted between data blocks,having almost the same BER performance.OC-FDE combined with parallel interference cancellation(PIC),named OC-PIC-FDE is a low complexity frequency-domain implementation method,with good BER performance.Based on the method,this paper proposed the improved method,by inferring the MMSE factors related to the user,jointing MMSE and PIC.The simulation results show the improved method has the same complexity compared with OC-PIC-FDE,but the BER performance is better.
