Abstract
Official abstract text for this publication.
According to various embodiments, devices and methods disclosed herein include performing, using a processor, a linear operation on a first plurality of channel frequency responses and a plurality of corresponding predictor coefficients to estimate a new channel frequency response. Each of the plurality of corresponding predictor coefficients may be updated based on an error value and a second plurality of channel frequency responses to obtain an updated predictor coefficient. The error value may be computed based on an estimated current channel frequency response and a predicted current channel frequency response. The new channel frequency response may be used to equalize a received modulated signal including a single-carrier modulated signal, e.g., a signal modulated using a vestigial sideband modulation scheme, or a quadrature amplitude modulation scheme.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: storing, in a memory, a first plurality of channel frequency responses and a plurality of corresponding predictor coefficients, wherein at least one of the plurality of corresponding predictor coefficients is a direct function of one or more particular frequencies; updating, using a processor, at least one of the plurality of corresponding predictor coefficients based on an error value to obtain an updated predictor coefficient for an…
