US 2014/0007108 A1 · METHOD AND APPARATUS FOR CONTROLLING POWER CONSUMPTION OF TURBO DECODER

Abstract

Embodiments of the present invention disclose a method and an apparatus for controlling power consumption of a TURBO decoder, which relate to the field of wireless communications technologies, can control a peak operation amount of the TURBO decoder to be within a certain range, and avoid occurrence of greater peak power consumption during a work process of the TURBO decoder, thereby lowering the manufacturing cost of a device using the TURBO decoder. The method of the present invention includes: determining size of a transmission block; determining, according to the size of the transmission block, the number of iteration times required for the TURBO decoder to process the transmission block, so as to control an operation amount required for the TURBO decoder to process the transmission block. The present invention is applicable to the TURBO decoder.
