Fig. 2From: A novel detector based on EM algorithm for multiple-mode OFDM with index modulationComparison of BER performance for MM-OFDM-IM (n=8, BPSK/QPSK). Figure 2 shows the comparison results of ML, EM, SW, and LCML detectors in terms of BER with the BPSK and QPSK modulation for MM-OFDM-IMBack to article page
