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.

此程序用来一个BPSK的调制信号。程序后面都有详细的注解，帮助理解！(This program is used to a BPSK modulated signal. Procedures are followed with detailed comments, to help understand!)
