Abstract
Due to its high spectral efficiency, high data rate and robustness against fast fading, orthogonal frequency division multiplexing (OFDM) is widely preferred in contemporary communication systems. But OFDM suffers from the problem of high peak to average power ratio (PAPR), which leads the power amplifier to operate in non-linear region, resulting in in-band and out-band distortion. This paper presents the construction of 1024-QAM, OFDM signal with low PAPR. The 1024-QAM code has been represented as a weighted sum of five Quadrature Phase Shift Key symbols.
