ABSTRACT:
A Reed-Solomon decoder for use in ATV is disclosed. The Seed-Solomon decoder comprises: a clock generator for generating a faster RS clock as much as t than a symbol clock; a FIFO buffer for latching the received symbol according to the RS clock; a syndrome calculator for calculating syndrome values from the received symbol according to the RS clock; a syndrome selector for selecting one of the syndrome values supplied from the syndrome calculator and "0.times.00" value according to a syndrome selecting signal; an error locator polynomial calculating unit for calculating coefficients of an error locator polynomial by using the syndrome values supplied from the syndrome selector according to the RS clock and supplying the coefficients and the highest order thereof; an error corrector for generating an error value by using the syndrome values and the coefficients of the error locator polynomial according to the RS clock and supplying an error-corrected recovered symbol by adding the error value to the received symbol supplied from the FIFO buffer; and a controller for generating a plurality of control signals for controlling the syndrome calculator, the syndrome selector, the error locator polynomial calculating unit, and the error corrector.
