In this paper, a MMSE based signal detector with interference cancellation (MMSE-IC) is proposed for a two-way relay channel using the decode-and-forward strategy, including two single-antenna source nodes and a multiple-antenna relay node. It is demonstrated that by using the proposed MMSE-IC detector, the BER at the relay when extracting the information of the two source nodes in the multiple-access...
Joint parallel interference cancellation (PIC) detection and power control scheme for multi-antenna systems is proposed in this paper. At the receiver, the Minimum Mean-Squared Error (MMSE) detector is utilized in the first stage, and its output is used to reconstruct the interference between antennas. Power control methods are proposed to help with the interference reconstruction at the receiver...
Two power control schemes for CDMA systems using a MIMO-based space-time signal processing technique, space-time mapping (STM), are proposed in this paper under slow fading scenarios, both for an individual link and in the presence of intra-cell interferers. Simulation results show that the proposed schemes provide a significant reduction in the bit error rate (BER) compared to that of no power control.
The uplink capacity of cellular systems, where the co-channel interference (CCI) limits the system capacity more than thermal noise, is investigated in this paper. We evaluate the overall system capacity under slow fading when space-time block codes (STBC) are employed. A power control technique suited for STBC is proposed to improve the bit error rate (BER) performance on the target link and the...
