SER Performance of Stepped θ-QAM in the Presence of Impulsive Noise

In this paper we derive symbol error rate (SER) expression of stepped θ-quadrature amplitude modulation (QAM) and analyze SER performance in the presence of impulsive noise. We show that the SER performance of the stepped θ-QAM is superior to that of square QAM in an impulsive noise environment, and validate the theoretical results with simulation ones through computer simulations.
