Abstract

In this paper, we propose a block coded modulation (BC3VT) technique to redact the peak to average power ratio (PAPR) iri OFDM systems. In the proposed technique, binary blocks are mapped to M-ury blocks and M-ary blocks of small sizes with low PAPR are selected. Large size Mary blocks with low PAPR are constructed by using the selected .small siae M-ary blocks. Similar to trellis coded modulation, with this technique variable rates ranging from 1 to a rate much higher than 1 of BCM can be obtained upon different requirements of the random error correction capability in the system, given that the PAPR 13 below a fixed value, PAPR gain is defined by comparing with the imcodcd OFDM system. Optimal coding gain for the BCM given a PAPR gain is also obtained in various cases.
