Compared with the well-known minimum mean-square error (mmse)-based turbo receivers, sorted QR decomposition (SQRD)-based data detection scheme has the advantages of lower complexity and better bit error rate (BER) due to the avoidance of matrix inversion and the use of successive interference cancelation. In this letter, we investigate SQRD-based data detection and soft interference cancelation in...
Spatial Modulation is a newly developed concept for multi-antenna systems, which could greatly reduce the signal processing complexity and hardware implementation burden faced by these systems today. To improve the spectral efficiency of spatial modulation system, a novel precoding scheme for downlink multi-user system is proposed in this paper. The precoding scheme not only cancels the inter-user...
Generalized selective combining (GSC) is a hybrid diversity technique involving first selective combining (SC) followed by maximal ratio combining (MRC). In this paper we study a new technology based on bit log-likelihood ratio (BLLR) which is better than the traditional GSC based on signal-to-noise ratio (SNR) in performance. WCDMA is one of the key technologies of the third-generation mobile communication...
