Abstract
Spectral information evaluation of the recently proposed multiple-pulse-position modulation (MPPM) scheme with variable Hamming weight is presented, its spectral properties being considered for the first time. In this sense, an original analytic expression for the power spectral density is obtained, including the continuous and discrete components of the spectrum, particularised for different code rates using Gaussian pulses with reduced duty cycle. Obtained results provide important considerations in the design of practical rate-adaptive optical wireless communications.
