matlab file is use to just liquild volumn, now need you to help check it.

We will consider trajectories that lie in a plane passing through the center of the planet, so that we permit no out-of-plane forces in the following analyses. The general nature of the trajectory and the variables describing it are shown in Figure 3-1 below

The simplest channel which we use in ideal case is AWGN channel and everyone knows that before starting siluation on the other part of the system we must simulate the AWGN channel.this is AWGN channel with a BPSK signal going through it and finally we detect the signal and plot BER vs SNR to compair with the theory.

一个很有用的程序，ML法能够很好的估计信号的信噪比,最大似然（ML）准则和最大后验概率（MAP）准则。( A very useful program, ML estimation method can be a good signal to noise ratio, Maximum Likelihood (ML) criteria and maximum a posteriori (MAP) criterion.)
