FSK一个简单易懂的调制程序，适合初学者，或者是需要简单不复杂的下载者(FSK modulation of a straightforward procedure, suitable for beginners, or simply do not need to download those complex)

美国国家航空和宇宙航空局(NASA)研制的跟踪和数据中继卫星系统(TDRSS)的正交信号发生器使用的是阶数为r=11的GOLD序列，序列长为2047，m序列优选对为4445和4005，利用Matlab程序构造出这个序列，并且验证信号的平衡标准，PACF(离散周期自相关函数)和PCCF(离散周期互相关函数)。通过Matlab2009A测试。(NASA developed tracking and data relay satellite system (TDRSS) use of orthogonal signal generator is the order of the GOLD for the r = 11 sequence of length 2047, m sequence pairs for the 4445 and 4005, use of Matlab program to construct the sequence, and verify the balance of the signal standard, PACF and PCCF. Testing by Matlab2009A.)
