RECEIVER SYSTEM ESTIMATING SYMBOL TIMING WITH FORWARD STRUCTURE AND TIMING ESTIMATION METHOD THEREOF

摘要

PURPOSE: A receiver system estimating symbol timing with a forward structure and a timing estimation method thereof are provided which increase the quality of the whole communication system by using only two samples per one period and estimating accurate symbol timing. CONSTITUTION: According to the receiver system estimating timing in a symbol unit by receiving a RF transmission signal, a matching filter(4) receives a baseband signal and separates it into a real part and an imaginary part. A timing estimation part(5) receives a signal being output from the matching filter, and then estimates symbol timing using every kinds of variables. A memory device(6) stores values of variables required in the operation of the timing estimation part, and outputs them according to the request of the timing estimation part. And an interpolator(8) interpolates symbol leading timing of the baseband signal by receiving the timing estimation value being output from the timing estimation part.
