Method and apparatus for managing a deinterleaving buffer in a mobile communication system adapted block interleaving

The present invention, the present invention as about operation of the deinterleaving buffer to reduce the size and number of buffers required for a receiver in a receiver of a mobile communication system using block interleaving and an apparatus are received through a wireless network a relative to the frame Reed-Solomon (RS) buffer the received frame in the course of operation of the deinterleaving buffer configured in the receiver of the mobile communication system into a plurality of sub-buffer to perform the decoding that the de input to the interleaving buffer address and RS decoding is set to be a frame cycle through the address buffer is output to the upper layer. And in the present invention, the de After the RS decoded by the sub-buffer units of a frame input to the interleaving buffer, RS the decoded frame e. G., One after the output to the upper layer in units of frames, and rotation at regular intervals frame the deinterleaving buffer and the type in a newly received frame to the input address having the same pattern as the output address is characterized in that the reduction of the size and number of buffers required for the receiving end. De-interleaving, a buffer, a frame, Reed-Solomon, the sub-buffer, decoding
