In this paper, we describe a coding technique for joint error correction and peak-to-average power ratio (PAPR) reduction of orthogonal frequency division multiplexing (OFDM) signals. This technique uses a standard block code for error correction and achieves PAPR reduction at the expense of lower error correcting capability. The technique is first(More)
— This report describes the PAPR problem in mul-ticode CDMA and investigates the effectiveness of using Reed-Muller and Kerdock codes to tackle this problem. The performance of Reed-Muller and Kerdock coded multicode CDMA system in the presence of amplifier nonlinearity are investigated. The performance of hard-decision decoding in AWGN and fading channels(More)
In this paper, we develop a soft-decision decoding algorithm for block codes using the k shortest paths algorithm. The performance of this algorithm is investigated and compared with other decoding schemes. The results show the proposed algorithm gives large gains over the generalised minimum distance (GMD) decoding algorithm and algebraic hard-decision(More)
