15188128 | 0908.0302 | 2009-08-03 | Polarization for arbitrary discrete memoryless channels | Channel polarization, originally proposed for binary-input channels, is generalized to arbitrary discrete memoryless channels. Specifically, it is shown that when the input alphabet size is a prime number, a similar construction to that for the binary case leads to polarization. This method can be extended to channels ... | [

Rather surprisingly it turns out that the classification of such solvable algebras can be reduced to the classification ... | [
