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 。
