Abstract :
Polar coding is a recent channel coding technique invented by Arikan to achieve the ´symmetric capacity´ of binary-input memoryless channels. Subsequently it was observed by Korada and Urbanke that such codes are also good for lossy channel coding, achieving the `symmetric rate distortion´ bound, when the representation alphabet is binary. In this note we extend this result to the case when the representation alphabet is q-ary, for q a prime number.
