We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation, phase-shift keying, and pulse amplitude modulation communications systems.We study the performance of a standard CFO estimate, which consists of first raising the received signal to the Mth power, where M is an integer depending on the type and size of the symbol constellation, and then applying the nonlinear least squares (NLLS) estimation approach. At low signal-to noise ratio (SNR), the NLLS method fails to provide an accurate CFO estimate because of the presence of outliers. In this letter, we derive an approximate closed-form expression for the outlier probability. This enables us to predict the mean-square error (MSE) on CFO estimation for all SNR values. For a given SNR, the new results also give insight into the minimum number of samples required in the CFO estimation procedure, in order to ensure that the MSE on estimation is not significantly affected by the outliers.

一本关于控制系统仿真的书的程序 1、文件夹1中的程序是书中的一些仿真。 2、文件2中的是最近做的预测控制、PID控制及逻辑控制的对比综合研究。 3、文件夹3中是与maltab通信的数据采集板的设计文件。包括串口设计、USB1.1及USB20设计。这是最新的设计资料，很有参考价值。 (About a control system simulation procedure one book, folders, one in the book are a number of procedural simulation. 2, document 2 are recent to do predictive control, PID control and logic control study Comparative General. 3, folder 3 are maltab communication with data acquisition board design document. Including the serial design, USB1.1 and USB20 Designed. This is the latest design information, useful reference value.)
