数据通信中的游程编码、解码方法。（编程背景为温室温度测量，限定在正负50以内）。已经编译通过。-Data communications in the run-length coding, decoding methods. (Programming background greenhouse temperature measurement, limited to within plus or minus 50). Has been compiled through.

In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered at the detector output.-In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered at the detector output.
