Closed-form error probability for M-ary chirp modulation in frequency-selective and -nonselective fading channels

A class of chirp signals for M-ary data transmission, referred to as M-ary chirp modulation (MCM), is considered. The performance analysis of this MCM over frequency-selective and -nonselective fading channels is carried out and closed-form error probability results that are easy for numerical computation are derived. The parameters that affect error performance are identified and illustrated. These analytical results are then compared using extensive Monte Carlo simulations. Specifically, the results are presented over Rayleigh and Nakagami-m flat fading and over Nakagami-m frequency-selective channels. It is shown that analytical results compare well with simulations.
