It explain about 3-phase active filter

小波阈值降噪的matlab代码 里面有两个程序 一个比较了软硬阈值去噪 另外一个对多层小波分解的阈值去噪做了对比(Wavelet threshold denoising matlab code there are two programs a relatively soft and hard thresholding is another multi-layer wavelet threshold denoising to do a comparison)

收集的关于粒子滤波的源码 里面有不同版本的粒子滤波例包括PF RPF EKFPF APF等等(Collected inside source on the particle filter have different versions of the particle filter cases, including PF RPF EKFPF APF, etc.)

In this paper, we present a novel data-based method for simultaneous Maximum Likelihood (ML) symbol and carrier-frequency o畇et estimation in Orthogonal frequencydivision multiplexing (OFDM) systems. Statistical properties introduced by the cyclic pre痻, a guard space between OFDM symbols, provide su眂ient information about the unknown parameters. It is shown that the redundancy introduced by this cyclic pre痻 allows the estimation to be performed without additional pilots. Simulations show that the performance of the frequency estimator is applicable in a tracking mode while the timing estimation can be used in an acquisition mode.

给出比较少见的16PSK的仿真算法，包括高斯信道，瑞利信道及线性时不变信道。其中，在瑞利信道中，给出了均衡前均衡后比较结果，从中可以看出均衡的效果(is relatively rare in the estimation algorithm, including Gaussian Channel, Rayleigh channel and the linear time-invariant channel. Of these, the Rayleigh Channel, is a balanced balanced ago after the results of the comparison, from which one can see the effect of balance)
