Figure 7From: Performance of opportunistic fixed-beam spatial multiplexing in OFDMA uplinkSimulated turbo-coded bit-error-rate performance. Turbo-coded bit-error-rate performance of the fixed beam approach (BeamBER) and the reference antenna approach (AntBER) as a function of the SNR in ITU Pedestrian B radio channel environment. BER plots are depicted at 25%, 50%, and 80% percentiles of the 15,000 simulated radio frames.Back to article page
