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.

实上,我们可以把系统框图中外编码器、交织器和内编码器三部分级联后的总体,看作一个级联码的编码器,同理,外译码器、去交织器和内译码器三部分级联后的总体构成了级联码的译码器。
本次仿真外编码采用(7,4)HAMMING码,内编码采用(2,1,3)卷积码。交织编码采用(7,4)卷积交织编码或循环等差交织编码。除特别说明外,交织编码采用前者即(7,4)卷积交织编码。
