Effects of Frequency-Selective Fading on Slow-Frequency-Hopped DPSK Spread-Spectrum Multiple-Access Communications
This paper is concerned with the performance of frequency-hopped spread-spectrum multiple-access communications in a fading environment. The data is transmitted on the carrier using differential phase-shift keying with multiple data bits per hop (i.e., slow frequency hopping). The frequency hopping and dehopping are noncoherent. Frequency-selective fading channels are considered for systems with various data pulse waveforms and channel delay power-density spectra. Analytical results for the average probability of error are presented, and numerical examples of the most interesting cases are given.
