This paper proposes M-ary circular theta-quadrature amplitude modulation (CTQAM) for M = 2(l), l >= 4, which is constructed by rearrangement of the signal points based on theta-QAM. We provide a construction method for the signal constellation of CTQAM and analyze the symbol and bit error performances of M-ary CTQAM in additive white Gaussian noise (AWGN) and Nakagami-m fading channels. Through computer simulations, we validate theoretical results.
