In this simulink model , 16-QAM 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 , 16-QAM 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.

RS232 是异步串行通信协议，广泛应用在计算机上。异步意味着它不会有任何单独的同步时钟信号，所以它必须同步本身对传入的数据-这是通过使用开始和停止脉冲。信号本身是略有不寻常的计算机，而是作为比正常 0V 到 5V 范围、 它使用 + 12V-12V-到这做是为了提高可靠性，并极大地增加了它可以工作在可利用的范围-不需要提供此确切电压摆动和实际使用 PIC 0V 到 5V 电压摆动和几个电阻可以做一个简单的 RS232 接口，通常会很好但并不保证与所有串行端口的工作。为此我设计了串行板能使用 MAX232 芯片，这是专为 5V 的逻辑级别之间的接口设计的芯片和 + 12V /-12V 的 RS232-它生成的 + 12V /-12V 内部使用电容器充电泵，并包括四个转换器，两个传输和两个接收，只采用的每-其他两个一个串行董事会明确标记为电路如果需要可以用别的东西。
