说明：  通过fft，求噪声功率谱的功率谱估计方法。(By fft, seeking the power spectrum of the noise power spectrum estimation method.)

粒子群算法之一，可在matlab中运行，分析一些函数的最优化问题(a kind of particle swarm, can be used in matlab)

该程序描述的是数字电视地面广播中卷积交织部分.因为是卷积交织所以最后结果中出现为的数值表示该值是前一包缓冲数据的数.但针对第一包数据做卷积交织时,这些零位置上最后确实自动补零.(The procedure is described in digital TV terrestrial broadcasting in parts of Convolutional Interleaver. Convolutional Interleaver because it is so final results for the numerical value is that the previous data on the number of packet buffer. But for the first packet data do Convolutional Interleaver These zero position is indeed the last automatic zero.)
