Abstract

Universal filtered multi-carrier(UFMC) technology is a candidate for 5G, without cyclic redundancy(CP) in transmission and inter-symbol interference(ISI) and inter-carrier interference(ICI) will occur under multi-path fading channels. To solve this problem, this paper proposed an equalization algorithm based on parallel interference cancellation. Firstly, according to the analysis, it obtained the mathematical expression of UFMC system interference under multi-path channel. Secondly, after using zero-forcing equalization, it used the data outside the reliable interval to approximate the reconstruction of adjacent carriers and inter-symbol interference according to the residual interference expression. Finally, it applied iterative interference cancellation to each carrier in parallel. Simulation experiments show that under multipath channel, the algorithm can reduce the bit error rate to a certain extent and improve the UFMC system performance.
