QAM_OFDM

The program implements the use of χ2 test for determining the distribution law of fluctuations of the signals. Hypotheses about the distribution of this or innogo parameter system, such as expectation, variance, probability density for a given level of significance accepted or refuted, in accordance with the results. The program implements two distributions: the exponential and Rayleigh.

运用复倒谱的方法,对信号进行去混响处理,将混响有效去除,被称为DCT法。(The method of using complex cepstrum of signal dereverberated will effectively remove the reverb, known as DCT method.)

This paper deals with the modeling of the statistical distribution of the effective gain of terminals. This incorporates both the characteristics of the antenna’s radiation pattern in the situation of use, and the characteristics of the local propagation environment. A frequency-wise and frequency-correlated log-normally-distributed effective-gain model is proposed as a standard model of wide – although not universal – validity. This is done mainly for the sake of simplicity and ease of use. This model is tested in a few exemplary cases of measured and simulated terminals, using a subset of the WINNER channel model for the local propagation.

simulink做的BPSK的调制与解调，信号源是随机信号与PN码扩频调制，最后结果与随机信号比较一致(simulink do BPSK modulation and demodulation, the signal source is a random signal with the PN code spread-spectrum modulation, the final result more consistent with the random signal)
