说明：  GMSK 信号在衰落信道中的频偏盲估计,学习阶段，大家共同进步(GMSK signal at the frequency of fading channel偏盲estimates, study phase, the common progress of U.S.)

该程序是对OFDM信号的频谱感知的循环特征检测方法，代码齐全，介绍详细(The program is the OFDM signal spectrum sensing cycle of feature detection, code complete, detailed description)

严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计 优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大，出来后学习率又还原 优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (BP network in strict accordance with the formula to design a matlab program, the optimized BP network design optimization 1: Design of the yyy, that is, o (k) formula, when the network into the flat areas (< 0.0001) increase learning rate large, after the optimization of learning rate reduction 2: v (i, j) = v (i, j)+ deltv (i, j)+ a* dv (i, j) )
