引入PEG（Progressive-edge-growth）算法来构造适合线性时间编码的LDPC校验矩阵，译码时采用简化最小和Min-Sum译码算法实现简化译码．仿真结果表明，该方法能够构造适合LDPC码的线性时间编码的下三角校验矩阵日，并且用此方法构造的LDPC码性能非常接近原来PEG算法构造的LDPC码．同时通过采用最小和Min-Sum算法降低译码复杂度．-The introduction of PEG (Progressive-edge-growth) algorithm to construct suitable for linear time encoding of LDPC check matrix, decoding simplified when the smallest and the Min-Sum decoding algorithm decoding simplified. Simulation results show that this method can construct LDPC codes suitable for linear time encoding on lower triangular calibration matrix, and constructed using this method the performance of LDPC code is very close to the original PEG algorithm constructed LDPC codes. At the same time through the use of the smallest and the Min-Sum decoding algorithm to reduce complexity.

　ModBus通讯协议分为RTU协议和ASCII协议，下面就ModBus RTU协议简要介绍如下：-ModBus RTU communication protocol into ASCII protocols and agreements, the following agreement on ModBus RTU briefed as follows :

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.
