TDSS-OFDM信号に対するサイド情報不要な復調方式の提案

抄録

The authors propose the side information-free and low-computational complexity reception technique for TDSS (Time Domain Sequence Superposition) taking advantage of the pilot subcarriers for side information estimation. The simulation results show the proposed receiver performs well over both AWGN channels and fading channels, i.e. loss-less BER performances are observed, while the computational complexity of the proposed receiver is nearly the same as the conventional OFDM receiver, which is less than 1/10 of the ML receiver.
