A bit error analysis of wideband OFDM systems that use high rate (0.67⩽R⩽0.95) low-density parity-check codes for bit-error protection is presented. Subcarrier modulation methods of BPSK, QPSK, and 16-QAM are implemented on channel models that include shadowed Rician fading and additive white Gaussian noise. The performance of different low-density parity check (LDPC) codes constructed through random and systematic methods is also compared
