The approximate minimum average symbol error rate (SER) precoder is designed for spatial multiplexing (SM) system in Ricean channels. Based on long-term channel state information (CSI), a closed-form solution that combines eigen-beamforming (E-BF) and power allocation is presented for correlated Ricean channel. Moreover, a simple precoder only based on K-factor and line-of-sight (LOS) departure angle...
The symbol error performance of spatially correlated multi-antenna systems is analyzed herein. When the transmitter only has statistical channel information, the use of space-time block codes still permits spatial multiplexing and mitigation of fading. The statistical information can be used for precoding to optimize some quality measure. Herein, we analyze the performance in terms of the symbol error...
