We present a new OFDM-based hybrid transmission scheme which is suitable for robust transmission in fast fading environments, where a reliable channel estimate is impossible or very difficult to obtain. Our scheme is based on the combination of noncoherently detected MFSK (M-ary frequency shift keying) and OFDM (orthogonal frequency division multiplexing). Furthermore, the subcarrier phases of this OFDM-MFSK scheme can be differentially modulated, leading to a hybrid transmission scheme where… CONTINUE READING
