摘要
The present invention is a digital multimedia broadcasting (DMB) leads for - low power by simplifying the circuit configuration of the RS decoder (Reed-Solomon decoder) Euclidean calculation cells according, in particular, using a single Euclidean algorithm arithmetic cell, to reduce the scale of the calculation circuit to Solomon decoding apparatus and to provide a modified Euclidean algorithm operation circuit, leads to the effective operation. ; Method according to the modified Euclidean algorithm operation circuit according to the invention is R (x) and Q (x) by the order value to be calculated in accordance with the conditions without calculating directly from the polynomial couple to each variable in the modified Euclidean algorithm stops it is easy to control and to repeat the loop once instead of 2 * t condition disappears. ; Digital Multimedia Broadcasting (DMB), Reed-Solomon decoding apparatus (Reed-Solomon decoder), the syndrome calculation circuit, calculates Euclidean algorithm cell, error location and error value
