Processing of Channel Coefficients of a Network

摘要

The present subject matter discloses a system and a method for processing of channel coefficients of networks. In one embodiment, the method includes ascertaining at least one probable synchronization position of a received sequence and projecting, by oblique projection, at least one given noise basis vector spanning a given noise space onto the null space, so as to determine a channel impulse response at the at least one probable synchronization position. Based on a criterion related to the channel impulse response, a synchronization point for the received sequence is identified from the at least one probable synchronization position. The method also includes determining the noise contribution at the synchronization point and determining the noise coefficient of the at least one given noise basis vector based on the noise contribution so as to recover a signal substantially similar to the originally transmitted signal.

1. A method of processing channel coefficients of a network, the method comprising:
ascertaining at least one probable synchronization position of a received sequence; projecting the received sequence, by oblique projection, so as to project basis vectors pertaining to a signal component onto a signal space, and at least one given noise basis vector onto a null space; determining a channel impulse response, based on the oblique projection, at the at least one probable synchronization position; identifying a synchronization point for the received sequence from the at least one probable synchronization position based on a criterion related to the channel impulse response; determining a noise contribution at the synchronization point by removing the signal component from the received sequence; determining a noise coefficient of the at least one given noise basis vector at the synchronization point based on the noise contribution; and recovering an original signal by compensating for the at least one given noise basis vector based upon the determined noise coefficient.
