实现网络ip通信传输，调用phone.dll，完成语音的通讯功能

In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.

天线是由韦伯斯特的字典定义作为"通常是金属设备 （比如杆或线) 发射或接收无线电波。"IEEE 标准定义的 天线 （IEEE Std 145 – 1983） ∗ 的术语定义的天线作为"一种手段发射或接收无线电波"。换句话说，天线是过渡自由空间与引导的设备，如图 1.1 所示的结构。指导设备或线路可能采取同轴线或空心管的形式 （导），它用来运输从发射的电磁能量源到天线，或从到接收器天线。在前一种情况，我们有发射天线和后者的接收天线。
