Abstract :
The authors have recently proposed a novel trellis shaping (TS) approach for peak power reduction of single-carrier signals. In this paper, we propose the use of M algorithm as well as sequential decoding with stack algorithm for the purpose of complexity reduction. Our comparative studies with the Viterbi algorithm (VA) show that the TS with these low-complexity algorithms can still offer substantial peak power reduction capabilities that are comparable to the VA.
