main_no_offset_2
假设截获了一段短波数字通信的信号，要求解调出最终的信息，每组解调出来后，将10组信息组合起来，恢复最终的信源输出数据。
先验信息：两组数据文件，编号为1、2，每组I、Q两路存放，格式为“int16”，采样率为9600Sa/s，其中第一组为单径情况，第二组为多径情况。
参数符合MIL-STD-188-110A标准；
同步序列为syn=seq.dat，BPSK调制；
接收机频率稳定度高于1e-6。
文件中有效信息总长度为333.75s，其中同步头长为5/12s，每时隙1/6s，训练序列占10 ，在数据之前；
交织方式为全交织，矩阵交织，列为1000，在比特级进行；
纠错码码率为1/2；
调制方式为BPSK、QPSK和8PSK中的一种，映射方式为二进制，BPSK相位偏移为0，其余两种为 。
(Suppose intercepted signal for a period of short-wave digital communications requires final demodulated information after each demodulated, combining 10 group information, to restore the final output data source.
Priori information: two sets of data file, numbered 1, 2, each I, Q two-way storage, the format is int16 , sampling rate 9600Sa/s, where the first group is a single path, the second group multipath situation.
Parameters meet MIL-STD-188-110A standard
