Abstract
Received baseband data signals, in the form of signals having at least one level transition per symbol indicative of symbol information state, are sampled (17) at a rate much higher than the symbol rate. The samples are used to control the direction of counting (20) of local clock (12) signals recurring at that higher rate during symbol subintervals of predetermined duration. Counts produced during adjacent subintervals are processed (FIGS. 4 and 5) to produce several different results such as recognition of the start of an asynchronously occurring data message, acquisition and tracking of symbol phase in the message, and detection of symbol information states.
