Abstract

In wireless communication systems Multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) is widely used scheme, But main limitation of OFDM-based systems it suffers from high peak-to-average power ratio (PAPR). In order to reduce high PAPR, a residue number system (RNS) is used MIMO-OFDM systems. Computational complexity and PAPR is reduced by using the properties of RNS. The RNS-based PAPR reduction scheme has not only much better PAPR reduction performance without restriction to modulation format, but also low computational complexity without side information in comparison with partial transmit sequence scheme.
