这是一个uwb用于体域网的信道仿真程序，可以进行仿真，它符合IEEE.802.15.4a，非常好！(This is a body area network for the uwb channel simulation program allows for simulation, it is consistent with IEEE.802.15.4a, very good!)

关于BPSK，QPSK，8QAM,16QAM，32QAM的调制解调程序。可作为单独模块加入到任何信道下，解调采用了两种方法。(On the BPSK, QPSK, 8QAM, 16QAM, 32QAM modulation demodulation process. As a separate module can be added to any channel, the demodulator uses two methods.)

(MATLAB) On the companion website, you will find in the directory Chap exercises/chapter3 a workspace ex3M2.mat. In this workspace, you will find waveforms of the words “we” and “be” (at 10000 samples/s) in the array we be 10k. The waveforms and a spectrogram of the waveforms are shownin Figure 3.33. To display the spectrogram andwaveform, use the function specgram ex3p19.m also in Chap exercises/chapter3. To listen to the waveform, use the MATLAB function sound.m.
