摘要
A method of storing survivor data generated while decoding channel polarization codes in a memory module includes setting a list size that corresponds to a number of decoder units used to decode the channel polarization codes, inputting a stream of input bits to the decoder units, and sequentially decoding the input bits. Each input bit is decoded using all previous input bits decoded before the each input bit. The method further includes selecting a plurality of survivor bits from among the decoded input bits, and storing the selected survivor bits in the memory module in a binary tree configuration. The number of edges in each level of the binary tree configuration does not exceed the list size.
