Apparatus and method for generating a decoding clock signal in response to a period of write and read clock signals

摘要

Disclosed is an apparatus and a method for generating decoding clock signals in response to a period of write and read clock signals for decoding transmission data, which is suppressed in a form of punctured code at a code rate. The apparatus according to the present invention comprises a) a clock generator receiving a control signal and a code rate from a transmission part, for rearranging a suppressed data; b) a controller receiving a write clock signal from an external circuit and a read clock signal from the clock generator, for controlling a period of a read clock signal wherein the period of the read clock signal is correspondent to the number of data stored in the memory; c) a decoding clock generator receiving a system clock signal from an external circuit and the control clock signal from the controller, for outputting a decoding clock signal.
