不考虑多径干扰时在高斯白噪声和瑞利衰落信道条件下QPSK的调制解调过程， 并采用准分析法完成误码性能的计算。仿真过程包括仿真信号产成，滤波器设置，QPSK调制，加入高斯白噪声，通过锐利信道衰落，QPSK解调，误码率计算等几部分(Not consider multi-path interference at the white Gaussian noise and Rayleigh fading channel under the conditions of the QPSK modulation and demodulation process and the use of quasi-analysis method to complete the calculation of BER. The simulation process includes the middle class into a simulation signal, filter settings, QPSK modulation, by adding Gaussian white noise, through the sharp decline in channel, QPSK demodulation, bit error rate calculation and other parts)

he rational is simply to fit a mathematical model to the ISI distribution that includes a component to model the refractory period. If a neuron is well isolated, it must exhibit some refractory period. If instead, it is multi- unit, then it will exhibit instead something similar to a poisson process in which there is no refractory period, or at least large probability of inter-spike intervals at the shortest intervals.
