Parallel-and-Serial
并行和串行级联码已成为一种实用的方法，取得了良好的性能。在此论文中，我们将介绍并行和串行级联单奇偶校验乘积码。我们对这种码的码重分布进行了分析，其性能是有界的。仿真的结果确定了在高信噪比情况下的性能界限。这种码（与一些变种）的性能证明对于降低译码复杂性和适当的短码长具有相当良好的效果。(Parallel and serial concatenated code has become a practical way to obtain good performance. In this paper, we will introduce the parallel and serial concatenated single parity check product codes. We re-distribution of this code code analysis, and its performance is bounded. The results of the simulation to determine the performance limits in the case of a high signal-to-noise ratio. Proof of performance of this code (with some variants) having a fairly good effect for reducing the decoding complexity and the appropriate short code length.)

fit_rayleigh_pdf
fit_rayleigh_pdf - Non Linear Least Squares fit of the Rayleigh distribution.
given the samples of the histogram of the samples, finds the distribution parameter that fits the histogram samples.fits data to the probability of the form: p(r)=r*exp(-r^2/(2*s))/s
with parameter: s
format:result = fit_rayleigh_pdf( x,y,W,hAx )
input: y - vector, samples of the histogram to be fitted
x - vector, position of the samples of the histogram (i.e. y = f(x,a))
W - matrix or scalar, a square weighting matrix of the size NxN where
N = length(y), or 0 to indicate no weighting is needed.
hAx - handle of an axis, on which the fitted distribution is plotted
output: result - structure with the fields
s - fitted parameter
VAR - variance of the estimation
type- weighted LS or not weighted LS
iter- number of iteration for the solution
