Partitioned List Decoding of Polar Codes: Analysis and Improvement of Finite Length Performance
Seyyed Ali Hashemi, Marco Mondelli, S. Hamed Hassani +2
Polar codes represent one of the major recent breakthroughs in coding theory and, because of their attractive features, they have been selected for the incoming 5G standard. As suc…
Capacity-Achieving Rate-Compatible Polar Codes for General Channels
Marco Mondelli, S. Hamed Hassani, Ivana Marić +2
We present a rate-compatible polar coding scheme that achieves the capacity of any family of channels. Our solution generalizes the previous results [1], [2] that provide capacity-…
Polar Codes: Robustness of the Successive Cancellation Decoder with Respect to Quantization
S. Hamed Hassani, Rudiger Urbanke
Polar codes provably achieve the capacity of a wide array of channels under successive decoding. This assumes infinite precision arithmetic. Given the successive nature of the deco…
On the Construction of Polar Codes
Ramtin Pedarsani, S. Hamed Hassani, Ido Tal +1
We consider the problem of efficiently constructing polar codes over binary memoryless symmetric (BMS) channels. The complexity of designing polar codes via an exact evaluation of…
Coupled Graphical Models and Their Thresholds
S. Hamed Hassani, Nicolas Macris, Ruediger Urbanke
The excellent performance of convolutional low-density parity-check codes is the result of the spatial coupling of individual underlying codes across a window of growing size, but…
The Compound Capacity of Polar Codes
S. Hamed Hassani, Satish Babu Korada, Ruediger Urbanke
We consider the compound capacity of polar codes under successive cancellation decoding for a collection of binary-input memoryless output-symmetric channels. By deriving a sequenc…
