Channel Polarization and Polar Codes; Capacity Achieving
A new proposed method for constructing codes that achieves the symmetric capacity (the capacity of the channel with the same probabilities for the inputs), ( ) I W , of any Binary Discrete Memoryless Channel W (B-DMC) will be introduced in this tutorial. This method is based on channel polarization. Channel polarization is the fact that we can synthesize N channels, ( ) { } :1 i N W i N ≤ ≤ , o...
متن کاملRate-Compatible Polar Codes for Wireless Channels
A design of rate-compatible polar codes suitable for HARQ communications is proposed in this paper. An important feature of the proposed design is that the puncturing order is chosen with low complexity on a base code of short length, which is then further polarized to the desired length. A practical ratematching system that has the flexibility to choose any desired rate through puncturing or r...
متن کاملConcatenated Capacity-Achieving Polar Codes for Optical Quantum Channels
We construct concatenated capacity-achieving quantum codes for noisy optical quantum channels. We demonstrate that the error-probability of capacityachieving quantum polar encoding can be reduced by the proposed low-complexity concatenation scheme. OCIS codes: (270.5585); (270.5565).
متن کاملConstruction of Capacity-Achieving Lattice Codes: Polar Lattices
In this paper, we propose a new class of lattices constructed from polar codes, namely polar lattices, to achieve the capacity 1 2 log(1+ SNR) of the additive white Gaussian-noise (AWGN) channel for any signal-to-noise ratio (SNR). Our construction follows the multilevel approach of Forney et al., where on each level we construct a capacityachieving polar code. The component polar codes are nat...
متن کاملRate-Compatible LDPC Codes
We present a new class of irregular low-density parity-check (LDPC) codes for moderate block lengths (up to a few thousand bits) that are well-suited for rate-compatible puncturing. The proposed codes show good performance under puncturing over a wide range of rates and are suitable for usage in incremental redundancy hybrid-automatic repeat request (ARQ) systems. In addition, these codes are l...
