Interference cancellation will become more important in future wireless communication systems due to various co-channel deployment scenarios and denser frequency reuse. In this study, an interference cancellation receiver is proposed which can be used for single-carrier frequency-division multiple access based systems. In the proposed receiver, impact of dominant interference (DI) is mitigated by an iterative blanking algorithm. If the DI is detected on the desired band, overlapping DI spectrum is blanked, followed by demodulation and regeneration of the desired signal. Afterward, the blanked overlapping samples are replaced by the corresponding samples of the regenerated signal. In order to improve the performance, demodulation and regeneration stages can be repeated multiple times. Performance of the proposed approach is compared with those of interference coordination and no cancellation through link-level and system-level simulations. © 2011 IEEE.
