ACCUMULATED PHASE MEASUREMENT USING OPEN-LOOP PHASE ESTIMATION

摘要

An apparatus and method for generating an accumulated phase measurement (406) of a communication signal over a predetermined time interval. A frequency estimate of the signal is generate (402); the frequency estimate is then converted to a coarse phase measurement (404, 642). A phase error is generated based on the frequency estimate (644); the phase error is then converted to a fine phase measurement (646). The coarse and fine phase measurements are summed to yield an accumulated phase measurement (648).
