Abstract

The present invention relates to apparatus and methods for encoding data and decoding data. For example, the present invention relates to an encoding device (102) for encoding data x of dimension k into a code word c of length n, wherein the encoding device (102) includes a processor (102a) configured to be based on Equation c=uA, the data x is encoded using a C(n,k,d) code, wherein the code C(n,k,d) has a length n and a minimum distance d, where, where, m h is an integer, h=1,...,s, where, if then 0≤j i < k-1, where F is the set of n-k frozen bit indices of the code C(n, k, d), and if i ∈ F, where is the constraint derived from the solution of the equation matrix, where φ i is the index of the row of said matrix having the last non-zero element in column i, and where is the precoding matrix, and where A is the matrix defined based on, and where denotes the m-th Crow of matrix Q with itself Kronecker product.

Description

technical field [0001] Generally, the present invention relates to data encoding and decoding in communication systems. More particularly, the present invention relates to an apparatus and method for encoding data and decoding data using a polar code or subcode based code. Background technique [0002] Reliably transmitting data over noisy communication channels often requires the use of some kind of error-correcting code. Polarization codes are shown to achieve Shannon capacity for many channels (see E. Arikan, "Channel polarization: A method for constructing capacity realization codes for symmetric binary input memoryless channels achieving codes for symmetric binary-input memoryless channels), IEEE Trans. on Inf. Theory, Vol. 55, No. 7, pp. 3051-3073, July 2009). However, the performance of polar codes with practical parameters is often unsatisfactory. [0003] Polar subcodes have emerged (see P. Trifonov and V. Miloslavskaya, "Polar subcodes", IEEE Journal on Selected...
