The LQ Decomposition for Linear Precoder Design with the SIC Detection

摘要

In this paper, we propose a novel linear precoding design that combines the LQ decomposition pecoder with the detection of the successive interference cancellation (SIC) for the V-BLAST (Vertical Bell Labs Layered Space-Time) system. Our scheme can usually get a perfect detection sequence which is very convenient to mitigating the error propagation, and achieves better bit error rate (BER) performance compared with the conventional schemes.
