Query: Non Binary Polar Codes with Equidistant Transform for Transmission over
  the AWGN Channel   Finding fast polarizing transforms is an important problem as polar codes
suffer from slow finitelength performance. This paper considers non binary
polar codes for transmission over the AWGN channel and designs polarizing
transforms with better distance characteristics using a simple procedure for
signal sets. The main idea of the paper is to define Equidistant Polarizing
Transforms and show that they achieve the best distance spectrum bound. We
provides an example of such transform for q = 5. In this case PSK-type signal
set is used. Finally, we show performance gains and some comparison with other
methods.
