A receiver controller configured to control a receiver in receipt a signal comprising a series of time-consecutive symbols is disclosed. Each symbol includes an FFT window and a guard interval and the guard interval includes a cyclic prefix or postfix. The receiver controller is configured to control the receiver to acquire at least one signal parameter. The receiver controller is also configured to, based on a plurality of samples of the received signal, each sample having a predetermined sample length, determination of a plurality of correlation values based on pairs of the plurality of samples, said pairs of samples separated in time by a predetermined separation number of samples.

The present invention concerns a method for cancelling a narrow band interference in a single carrier signal. The method comprises the steps executed by a receiver of: receiving the single carrier signal and transforming the single carrier signal into received symbols, transforming the received symbols from the time domain to the frequency domain into received symbols in the frequency domain, determining a signal and thermal noise power estimation based on the received symbol powers in the frequency domain, estimating variances of the narrow hand interference from the signal and thermal noise power estimation and the received symbol powers in the frequency domain, equalizing the received symbols in the frequency domain or symbols derived from the received symbols in the frequency domain taking into account the estimate of the variances of the narrow band interference.

Described are phase adjustment circuits for clock and data recovery circuits (CDRs). Systems and apparatuses may include an input to receive a serial data signal, an edge data tap to sample transition edges in the serial data signal for generating a data edge detection signal, a CDR circuit including a phase detector to receive the serial data signal and the data edge detection signal, and to output a phase lead/lag signal indicating the phase difference between the serial data signal and the data edge detection signal, and a phase adjustment circuit to generate phase lead/lag adjustment data. The CDR circuit is to output a recovered clock signal based, at least in part, on the phase lead/lag signal adjusted by the phase lead/lag adjustment data.

Techniques for smoothing a signal are disclosed. The system partitions the portion of the data sequence into a stable subsequence and an unstable subsequence of data points. The system applies a rate of change exhibited by the stable subsequence to the unstable subsequence to create a smoothed, more stable subsequence.

Techniques for smoothing a signal are disclosed. The system partitions the portion of the data sequence into a stable subsequence and an unstable subsequence of data points. The system applies a smoothing function that replaces the unstable subsequence of data points with another subsequence of data points, based at least in part on the stable subsequence, to create a smoothed, more stable subsequence.

A method may include receiving, at a receiver, a signal comprising a symbol. The method may include performing, at the receiver, a first operation using a number of most significant bits by gating a selected number of least significant bits. The method may include detecting, at the receiver, a symbol value of the symbol using the first operation.
