[Other] BCFO DL : 0: 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.

[Software Engineering] GMSK DL : 0: GMSK是高斯滤波的最小频移键控的简称，基本的工作原理是将基带信号先经过高斯滤波器成形，再进行最小频移键控(MSK)调制。由于成形后的高斯脉冲包络无陡峭边沿，亦无拐点，因此频谱特性优于MSK信号的频谱特性。-GMSK Gaussian filter is the smallest FSK abbreviation, the basic working principle is to base-band signal to pass Gaussian filter shape, and then a minimum frequency shift keying (MSK) modulation. After forming as a result of the Gaussian pulse envelope without the steep edge, there is no inflection point, so the spectrum characteristics of the spectrum than MSK signal characteristics.
