Receiver with offset compensation varies carrier frequency deviation detection signal and/or carrier frequency capture range until carrier phase offset is smaller than adjustable threshold

摘要

The device has a carrier frequency loop that generates a frequency deviation detection signal, a carrier phase loop that generates a phase deviation detection signal and an offset control circuit that varies the carrier frequency deviation detection signal and/or a carrier frequency capture range with an offset control signal until a carrier phase latch detection circuit indicates that the carrier phase offset is smaller than a threshold. The device has a carrier frequency loop (18) that generates a carrier frequency deviation detection signal, a carrier phase loop (32) that generates a carrier phase deviation detection signal and an offset control circuit (29) that varies the carrier frequency deviation detection signal and/or the second carrier frequency capture range with an offset control signal until a carrier phase latch detection circuit (21) indicates that the carrier phase offset is smaller than an adjustable threshold.
