Title: LOCATION OF INTERLEAVER WITH LDPC CODE
Abstract:
Concepts and schemes pertaining to location of interleaver with low-density parity-check (LDPC) code are described. A processor of an apparatus encodes data to provide a stream of encoded data. The processor also rate matches the encoded data to provide a rate-matched stream of encoded data. The processor further interleaving the rate-matched stream of encoded data. In rate matching the encoded data, the processor buffers the stream of encoded data in a circular buffer, with the circular buffer functioning as a rate matching block that rate matches the stream of encoded data. In interleaving the rate-matched stream of encoded data, the processor performs bit-level interleaving on the rate-matched stream of encoded data to provide a stream of interleaved data.
