Study of Non-Uniform Channel Polarization and Design of Polar Codes with Arbitrary Rates
In this paper, we present the concept of non-uniform channel polarization and
a scheme for rate-compatible polar code construction for any codeword length
using additive white Gaussian noise (AWGN) channels and the successive
cancellation (SC) decoder. A Non-Uniform Polarization technique based on the
Gaussian Approximation (NUPGA) is developed and an efficient rate-compatible
design technique is devised to choose the best channels for transmission by a
process of re-polarization of the codeword with the desired length. Simulations
illustrate the proposed NUPGA design against existing rate-compatible
techniques.Comment: 7 pages, 6 figure
