此程序为非二进制LDPC 码的仿真程序. 信道为AWGN, 调制方式 是BPSK.-This program is used to simulation nonbinary LDPC codes over AWGN channel and BPSK modulation. The decoding algorithm is in the probability domain and with the fast Hadamard transform in the check node.

modbus 采用Rtu方式时检测寄存的值.-modbus test using Rtu way that the value of storage.

C program to calculate the BER performance of BPSK modulation in an AWGN channel. The program takes the file "BPSK" containing voltage levels and passes it in an AWGN channel with a given SNR. The received message is then Hard decision decoded and the bit error rate is calculated. The BER over different SNR is calculated. THe output values can be used to draw a BER vs SNR(dB) curve.
