On companding techniques for PAPR reduction in DCT SC-FDMA system in the presence of CFOs

Popis výsledku v původním jazyce

In the single carrier frequency division multiple access (SC-FDMA) system, the use of discrete cosine transform (DCT) instead of discrete Fourier transform (DFT) has shown improved bit error rate (BER) performance. Nevertheless, peak-to-average power ratio (PAPR) in the DCT-based SC-FDMA system is higher than that in the DFT-based system. This paper investigates the performance of various companding schemes to reduce PAPR in DCT-based SC-FDMA systems by considering carrier frequency offsets (CFOs). Simulation results, considering parameters like BER, PAPR, and power spectral density (PSD), are provided to find the best companding tech-nique. Furthermore, the results have been validated in a real-time indoor channel using a wireless open-access research platform (WARP) hardware.
