SYSTEMS AND METHOD FOR FINITE RATE OF INNOVATION CHANNEL ESTIMATION

摘要

This disclosure provides systems, methods and apparatus for finite rate of innovation channel estimation. In one aspect an apparatus for equalizing received signals is provided. The apparatus comprises a signal per-processing unit configured to process received pilot signals transmitted through a sparse channel into at least one composite signal. The at least one composite signal further includes a plurality of signal peaks. The apparatus further comprises a Fourier transform unit configured to transform the at least one composite signal into frequency-domain data and a channel estimation unit configured to estimate at least one delay value and at least one peak value from the frequency-domain data.
