Abstract:
An orthogonal frequency division multiplexing (OFDM) system provided for communication includes an OFDM transmitter and an OFDM receiver. The OFDM transmitter may be configured to transmit OFDM signals through a communication channel and may include a channel encoder configured to encode a plurality of information bits and an interleaver configured to interleave the channel-encoded information bits. The OFDM transmitter may also include a mapper configured to map the interleaved channel-encoded information bits into mapped multi-level symbols. The OFDM transmitter may also include a dispersive encoder that is configured to dispersively encode the mapped symbols. The OFDM receiver may be configured to receive the transmitted OFDM signals and to decode the received OFDM signals iteratively based on soft decision methods.
