接收部分从信道接收信号。经基带滤波、短码解扩、沃尔什解调、解扰、去交织和维持比译码，输出解调后的信号。各通信模块和发射机的相关模块设计类似。(Receiving part receives signals from the channel. The baseband filtering, short code solution extender, Walsh demodulation, cross talk, go to interweave and solution than decoding, maintain the output signal after demodulation. Various communication module and the related module design similar transmitter. )

In MATLAB, usually we use function bvp4c() to solve boundary value problem (BVP) of ODE. However, we also can use function ode45() to solve BVP of ODE too. However, ode45() needs all initial values at one point. Therefore we have to construct an auxiliary function, whose input argument is the missing initial value and the return output is the given boundary value, Then we can call function fsolve() to get the missing initial value. This method is particularly efficient it the ODE has one or more parameters. Also this method is essentilal for GNU Octave, because whose function bvp4c() is not programmed for parameter ODE yet.
