Adaptive quantization for spectrum exchange information in mobile cognitive radio networks
To reduce the detection failure of the exchanging signal power onto the OFDM subcarrier signal at uniform quantization, dynamic subcarrier mapping is applied. Moreover, to addressing low SNR's wall less than predetermine threshold, non-uniform quantization or adaptive quantization for the signa...
