Method for estimating symbol timing in feed-forward manner

摘要

A receiving system for estimating symbol timing in a feed-forward manner comprises: a matched filter for receiving baseband signals and dividing them into real and imaginary numbers; a symbol timing estimator for receiving signals from the matched filter and estimating symbol timing using variables; a storage unit for storing the variables and outputting them according to requests of the symbol timing estimator; an interpolator for receiving a symbol timing estimate from the symbol timing estimator, and interpolating symbol-reading timing of the baseband signal; a delayer for delaying the baseband signal input to the interpolator; an RF/IF signal processor for receiving RF signals and performing RF/IF signal processing; and a baseband converter for converting the signal output from the RF/IF signal processor into baseband signals, and outputting them to the matched filter.
