Abstract
Apparatuses and methods are disclosed for a communication device associated with a wireless transmission. In one embodiment, a method includes performing one of a low-density parity check, LDPC, decoding process and an LDPC encoding process by loading a set of bits, in parallel, into a plurality of registers, the set of bits being distributed among the plurality of registers; one of de-interleaving and interleaving the loaded set of bits within the plurality of registers by rearranging the loaded set of bits into one of a de-interleaved and an interleaved set of bits; and after the set of bits is rearranged into the one of the de-interleaved and the interleaved set of bits within the plurality of registers, writing the one of the de-interleaved and the interleaved set of bits, in parallel, from the plurality of registers to memory.
