Abstract :
Previous research suggests combining partial transmit sequences (PTS) to reduce the peak-to-average power ratio of orthogonal frequency division multiplexing (OFDM). PTS involves forming several blocks of carriers and multiplying each by a constant phase factor. The phase factors are optimised to minimise the peak signal power. This paper proposes a new optimisation criterion for this purpose and provides simulation results to show the achievable peak factor reduction
