DQPSK

宽带模糊函数，用来分析带宽很宽的信号，像LFM等，这个例子对大家有帮助！(Wideband ambiguity function is used to analyze a wide-bandwidth signals, such as the LFM, the example of the help!)

Gabor变换子函数，有详细注释，采用高斯窗，绝对可用(Gabor transform subroutine, detailed notes, using the Gaussian window, absolutely useful)

产生、播放DTMF音频，基于Goertzel算法估计DTMF音频，完成双音多频(DTMF)信号的检测(Generating, playing DTMF tones, DTMF tones based on the estimated Goertzel algorithm to detect the completion of dual tone multi-frequency (DTMF) signal)

时变参数的粒子群优化的matlab实现，可用于解决多种连续优化问题(A flexible implementation of PSO algorithm with time-varying parameters. Algorithm is suitable for solving continuous optimization problems. Special care has been taken to enable flexibility of the algorthm with respect to its parameters and to initial population selection. Detailed logging of the algorithm performance during the search is also enabled. )
