Abstract

We investigate CAZAC sequences with positive and negative chirp for the use as training sequences in data-aided channel estimation. While both sequences show the same linear performance, the right choice of chirp is critical in case of nonlinear transmission. A performance difference of up to 2 dBQ was experimentally verified.
