[文件格式] 5.--PSK-Demodulation-(Part-1)
说明:Phase-shift keying (PSK) is a modulation process whereby the input signal, a binary PCM waveform, shifts the phase of the output waveform to one of a fixed number of states. The demodulation process can be divided into three major subsections, as<lala> 在 2025-06-07 上传 | 大小:81kb | 下载:0

说明:Thus PSK systems require less transmitted power for a given probability of error than ASK or FSK systems. Synchronous detection of PSK signals is required,due to the absense of a large carrier component.Carrier recovery is there for emore compl<lala> 在 2025-06-07 上传 | 大小:28kb | 下载:0
