Figure 5From: Low-complexity WLMMSE channel estimator for MB-OFDM UWB systems BER vs. SNR for WLMMSE and Lr-RWLMMSE estimators over CM2 channel model. BER, bit error rate; WLMMSE, widely linear minimum mean square error; Lr-RWLMMSE, low-rank real-valued widely linear minimum mean square error.Back to article page
