摘要：

We consider the use of wideband systems for the fixed point-to-point transmission of coded data with low bit-error rate requirements. A system is defined which is based on OFDM transmission with PSK and QAM subcarrier modulation, error control coding using low-density parity-check (LDPC) codes, and channel equalization to reduce intersymbol interference from a fading channel. Tradeoffs between modulation parameters and equalization complexity are also discussed. High rate LDPC codes are considered for this system.
