Modified shapiro-rudin sequences for SLM-PAPR reduction in wireless OFDM systems

Using selected mapping (SLM), chaotic-binary (CB) sequences have been successfully applied to reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. However, high computational complexity associated with the construction of CB sequences make them unattractive in practical system. This paper presents an alternative source of SLM sequences, namely Modified Shapiro-Rudin (MSR) sequences. Simulations compare PAPR reduction performance and computational complexity of MSR sequences over CB and conventional Shapiro-Rudin (SR) sequences. Results demonstrate that MSR sequences provide equivalent PAPR reduction to CB sequences but have the advantage of reduced computational complexity.
