Abstract
To reduce the PAPR of multi-carrier transmission, we propose a new scheme by reordering the null-subcarriers and data-subcarriers. This new method shifts the “innermost” null subcarriers among different data-subcarriers to minimize the PAPR. Considering the practicability for implementation, we propose the “Simplified” version, which degrades the computational load by applying proposed shifting scheme only to the subblock with the largest PAPR. The proposed “Simplified” method is distortionless, does not affect the constellation at the data-subcarriers, maintains better PAPR reduction and BER reduction performance while keeping low computational complexity, needs less CSI, can collaborate with most other PAPR-reduction methods, and can be compatible with existing standards.
