Multilevel polarization for nonbinary codes and parallel channels
Polar codes nonbinary channels parallel channels
2011/9/20
Abstract: We study polarization for nonbinary channels with input alphabet of size q=2^r,r=2,3,... Using Arikan's successive cancellation decoding, we prove that the virtual channels that arise in the...
Multilevel Polarization of Polar Codes Over Arbitrary Discrete Memoryless Channels
Polar Codes Memoryless Channels Information Theory
2011/8/30
Abstract: It is shown that the original construction of polar codes suffices to achieve the symmetric capacity of discrete memoryless channels with arbitrary input alphabet sizes. It is shown that in ...
