| Abstract: | On orthogonal frequency division multiplexing(OFDM) of PAPR,an improved compression and expansion C transformation method was applied to reduce peak-to-average power ratio(PAPR) in OFDM systems.The improved algorithm was the compression and expansion in the original C transformation method,based on certain parameters through appropriate changes to achieve the objective of further reducing PAPR.Simulation results showed that the improved algorithm was more effective in inhibiting the PAPR,the system's error ... |
