Figure 5From: A polarity comparison timing synchronization estimation for MB-OFDM-based UWB systemsCorrelation difference output for preamble 3 (or equivalently 4). (A). CM1, SNR = 10 dB. (B) CM1 noiseless. (C). CM2, SNR = 10 dB. (D). CM2, noiseless. The received timing index varies from 0 to 1000.Back to article page
