An encoder for encoding source information into an encoded codeword used in a communication channel includes a data input to receive source data, a processor, and a memory to store an encoder program. The encoder program makes the processor to encode the source data into a turbo product coding (TPC) structure, and the TPC structure comprises a data block corresponding to the source data, a first parity block including a first column part, a first corner part and a first bottom part, the first parity block being arranged so as to cover a right end column of the data block, a right bottom corner of the data block and a bottom row of the data block by the first column part, the first corner part and the first bottom part, and a second parity block having a row parity block, a joint parity block and a column parity block.

Certain aspects of the present disclosure provide techniques for Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining a minimal list size to use in list decoding operations for reducing resource consumption (e.g., compute, memory, and power) at a decoder. A method includes receiving a codeword comprising a plurality of channel bits encoded with an error-correcting code, the plurality of channel bits comprising, at least, a plurality of information bits, determining a payload size of the codeword, determining a channel capacity metric for the plurality of channel bits, determining a minimal list size for a list decoding operation based on at least the payload size and the channel capacity metric; and performing the list decoding operation on the codeword based on the minimal list size to obtain the plurality of information bits.

In one embodiment, a method includes loading first data into a first buffer of an interposer during a first time period and loading second data into a second buffer of the interposer and performing a first decoding operation on the first data using a first decoder during a second time period. The method includes loading third data into a third buffer of the interposer, performing the first decoding operation on the second data using the first decoder, and performing a second decoding operation on the first data using a second decoder during a third time period. Moreover, the method includes loading fourth data into a fourth buffer of the interposer, performing the first decoding operation on the third data using the first decoder, and performing the second decoding operation on the second data during a fourth time period. The first and second decoding operations are C1 or C2 decoding operations.
