Problems solved by technology

In other words, bits encoded in a high-capacity subchannel will experience a channel with a high Signal-to-Noise Ratio (SNR) and will have a relatively high reliability or high probability of being correctly decoded, Whereas bits encoded in a low-capacity sub-channel will experience a channel with a low SNR and will have low reliability or a low probability of being correctly decoded

Embodiment Construction

[0037] figure 1 is a schematic example showing how the kernel G can be 2 100 produces a graph of a polar encoding generator matrix. It should be noted that figure 1 is the example. Other forms of kernels are also contemplated in this disclosure. According to aspects of the present disclosure, polarization comes from a "nested" approach, where a generator matrix is ​​created from a kernel (or combination of kernels).

[0038] can be derived from the seed matrix F=G 2 A Kronecker product matrix of 100 forms a polar code. For a length N=2 m The polar code of the code word, the generator matrix is figure 1 The 2-fold Kronecker product matrix in 102 and 3 times the Kronecker product matrix 104 is an example of a polar encoding generator matrix. can be extended figure 1 The generative matrix method shown to produce m-fold Kronecker product matrices

[0039] figure 2 is a diagram showing an example use of a polar encoding generator matrix for generating a codewo...

Abstract

The input bits are encoded into a codeword comprising the encoded bits. The encoding consists of encoding the first set of polarization-encoded matrices G of the prime dimension Y Y Applied to the input bits to generate the output bits, and the second set of polar encoding matrices G of prime dimension Z Z applied to the output bits to generate the codeword. G X and G Y One or both of can be non-2-by-2 matrices. This paper also discusses other aspects of such core design and code construction in detail, including reliability and selection of subchannels for code construction, non-CRC-aided error correction, and code truncation and puncturing.
