Abstract
A receiver for input signals generated using a phase-based modulation scheme such as bipolar-phase shift-keying (BPSK) modulation or quadrature-phase shift-keying (QPSK) modulation. The receiver can sample the input signal using one of at least two different sampling frequencies that are selected such that at least one of the sampling frequencies is not harmonically related to the carrier frequency of the input signal by a ratio of small numbers. In this way, the receiver can avoid interference patterns that can result when the sampling frequency and the carrier frequency are harmonically related. In one embodiment, the receivers are hard-limiting receivers that are suitable for use in the remote nodes of fiber-to-the-curb (FTTC) communication systems, where low-power receivers are desirable.
