Abstract

Managing the peak-to-mean envelope power ratio (PMEPR) of orthogonal frequency-division multiplexed (OFDM) transmissions is a difficult but essential problem for practical and low-cost applications of OFDM. A promising coding technique generates OFDM signals from Golay complementary sequences in first-order Reed-Muller (RM) codes. In this paper we will construct a 16-QAM code with PMEPR les 7.2. The code enjoys simple encoding method, has good error correction capability, and it can be decoded with a low-complexity minimum-distance (MD) algorithm
