Abstract

Universal filtered multi-carrier (UFMC) system is sensitive to frequency offset through the channel that destroys the orthogonality between subcarriers,

resulting in inter-carrier interference (ICI) which increases BER.

This paper presents a study of UFMC system after applying one of the ICI self-cancellation techniques, which is the improved PWDC technique, which was used to correct the phase rotation error of received symbols in OFDM system, and then compares the performance of this technique with Standard UFMC and DC, PWDC, WCT techniques, in terms of BER and PAPR.

Simulation results prove that the improved PWDC technique gives better efficiency than other self-cancellation techniques and standard UFMC in reducing ICI and improving BER, but at the cost of PAPR which is increased by about 4.5dB compared to the standard UFMC system.
