这是21寸定位压合源代码(it s very inportent)

说明：  尽管瑞利和莱斯分布确实能够在很多情况下对信号通过衰落信道后的包络进行很好的建模，然而，在实际的无线环境测试中，发现Nakagami分布提供了更好的与实际测试的匹配度。(Although Rayleigh and rice distribution can model the envelope of the signal after passing through the fading channel in many cases, in the actual wireless environment test, Nakagami distribution is found to provide a better match with the actual test.)

Convolution Encoder and Decoder rate 1/2 MAP, step by step

包括相位编码（含二相BPSK和四相QPSK）、线性调频LFM、非线性调频NLFM、脉冲幅度调制(PAM)信号、带噪FSK频率编码信号等的信号源码，是很好的产生各种雷达信号的程序资源。(Including the phase encoding (including two-phase four-phase BPSK and QPSK), LFM LFM, non-linear FM NLFM, pulse amplitude modulation (PAM) signal with noise signals encoded FSK frequency signal source, is to produce a good variety of radar Program resources signals.)

Used function P(x) = 1+x− x2+0.2x3+0.1x4 and its known the values P(x)=[ -6.2 -8.3 -5.0 -1.1 1 1.3 2.2 8.5 27.4], in x= [-4 -3 -2 -1 0 1 2 3 4] to interpolate in the xi = − 4 + 0.1i, i = 0, 1, 2, . . . 80. Results are graphically compared!(Used function P(x) = 1+x− x2+0.2x3+0.1x4 and its known the values P(x)=[-6.2-8.3-5.0-1.1 1 1.3 2.2 8.5 27.4], in x= [-4-3-2-1 0 1 2 3 4] to interpolate in the xi = − 4+ 0.1i, i = 0, 1, 2, . . . 80.
