【简　介】:Developed during the early days of the deep space programs, phase-shift keying now finds widespread use in both military and commercial communication systems. For telemetry applications, PSK is considered an
efficient form of data modulation because it provides the lowest probability of error for a given received signal level, when measured over one symbol period. Terrestrial microwave radio links and satellite communication systems also frequently employ PSK as their modulation format.

【简　介】:The second subsection required for PSK demodulation is the symbol timing recovery, or STR circuitry. All techniques discussed here are data-derived; i.e., the timing information required to optimize for correct bit decisions is derived from the raw data itself. Additionally, only suboptimal techniques will be discussed. Optimal techniques developed for deep space telemetry applications [3] can be slow in acquisition when used for burst-mode modem operation, and are difficult and costly to implement.
