摘要：
UPF algorithm is compared to other filtering algorithm has higher precision and greater noise immunity, but because of its complexity, which greatly limits its application in real-time communication system. This paper introduces EPF and RPF algorithm and its improvements, and improved algorithm is applied to blind equalization in OFDM systems. Finally The simulation proved that the improved UPF algorithm, almost does not affect the filtering effect of the premise, greatly reducing the amount of filtering required to calculate and improve the numerical stability.
