    摘要: Provided are a method and apparatus for derate matching a rate-matched data. The received data is deinterleaved and derate matched at a time, without using input buffers or constructing input buffers in parallel. Thus, a total process time necessary for the deinterleaving process and the derate matching process is reduced, and the use of memories such as the input buffers is minimized.

    摘要: Provided is a rate matching apparatus. The rate matching apparatus includes interleavers, dummy bit removers, a bit collector, a memory and a selector. The interleavers interleave code blocks, respectively. The dummy bit removers remove dummy bits of the interleaved code blocks, respectively. The bit collector collects code blocks with the dummy bits removed by bit units, and divides a collected data bit stream into systematic data and parity data. The memory stores the systematic data and the parity data in parallel. The selector outputs in parallel a plurality of data bits which are selected from the systematic data and parity data of the memory.
