A software reconfigurable optical multiband UWB system utilizing a bit-loading combined with adaptive LDPC code rate scheme

•A bit-loading combined with ALCR algorithm is investigated in MB-OFDM UWBoF system.•A MZM with negative chirp parameter is utilized in MB-OFDM UWB system.•The ALCR algorithm can work effectively in MB-OFDM UWB system.•The SNR is improved by 2.79dB using ALCR when the code rate is 75%.•The Q factor...
