Abstract
The side information brought by some techniques to reduce the Peak - to - Average Power ratio (PAPR) of the Orthogonal Frequency Division Multiplexing (OFDM) systems such as the Selected Mapping (SLM) will affect on the spectrum usage. In this work, we proposed a method to eliminate this effect called Amplitude - Phase - Grouping (APG) method. The APG will subgroups the samples then a modification to the amplitudes and phases for these groups will be implemented. The data vector will be recreated again by recombining the groups to pass it to an Inverse Fast Fourier Transform (IFFT) process where the computational complexity bas been reduced around 96% compared to the SLM - technique. Simulation results proved the PAPR performance enhanced significantly with some effects on the Bit Error Rate (BER).
