1 A New Construction of 16-QAM Codewords with Low Peak Power

Authors: Jiaxiang Zhao

Abstract:

We present a novel construction of 16-QAM codewords of length n = 2k . The number of constructed codewords is 162×[4k-1×k-k+1] . When these constructed codewords are utilized as a code in OFDM systems, their peak-to-mean envelope power ratios (PMEPR) are bounded above by 3.6 . The principle of our scheme is illustrated with a four subcarrier example.

Keywords: Orthogonal Frequency Division Multiplexing (OFDM), Extended Rudin-Shapiro construction, peak-to-mean envelope power ratio (PMEPR)
