摘要 UPF滤波算法具有比PF算法更高的精度和抗噪声能力,但由于其计算复杂,不符合通信实时性的要求。为了改进算法的实时性,引入了平方根无迹粒子滤波算法(SRUPF),并对其进行改进,将改进算法应用于OFDM系统盲均衡中。最后经仿真表明,改进的UPF算法,在几乎不影响滤波效果的前提下,大幅减少了滤波所需计算量,并提高了数值稳定性。 UPF algorithm is more feasible and accurate than PF algorithm. But because of its complexity, it is not fit for the real-time communication. In order to improve the real-time quality, the square root unscented particle filter was proposed and improved. After that, the new algorithm was applied to the blind equalization in OFDM system. Finally, simulation results show that the new algorithm reduces UPF computation notably on the premise and almost does not weaken performance. At the same time, it increases the stability of the numerical value.
