摘要： The present invention discloses a method and apparatus to provide, effectively and robustly, a phase reference in phase-domain for digital phase-modulated signals. Not only the first-order but also higher order PLLs are delineated for robust and fast tracking of frequency errors and time-varying frequency errors between the transmitter and the receiver. This invention can be applied to any phase-modulated signal such as PSK, DPSK, π/4-DPSK, and CPM. The decoders with this invention can achieve close to the performance of coherent detection.Reference[1] D. Divsalar and M. K. Simon, “Multiple-symbols differential detection of MPSK,” IEEE Trans.

摘要： A speech detection method is presented, which includes the following steps. A first voice captured device samples a first signal and a second voice captured device samples a second signal. The first voice captured device is closer to a speech signal source than the second voice captured device. A first energy corresponding to the first signal within an interval is calculated, a second energy corresponding to the second signal within the interval is calculated, and a first ratio is calculated according to the first energy and the second energy. The first ratio is transformed into a second ratio. A threshold value is set. It is determined whether the speech signal source is detected by comparing the second ratio and the threshold value.
