The paper presents a investigation into the bit error rate (BER) performance of orthogonal chirp division multiplexing (OCDM) systems, utilising fading channel models such as Rayleigh, Rician, Nakagami-m (m=2), Weibull, and Jakes Doppler. The analysis is conducted across three receiver structures which are zero forcin…

Abstract We present enumeration formulas for double circulant (DC) codes of length $$2m$$ and four circulant (FC) codes of length $$4m$$ over the finite field $$\mathbb {F}_q$$ , with prescribed Euclidean hull dimension, assuming $$\gcd (m, q) = 1$$ . These formulas significantly generalize previous results that were…

The emergence of alternative multiplexing domains to the time-frequency domains, e.g., the delay-Doppler and chirp domains, offers a promising approach for addressing the challenges posed by complex propagation environments and next-generation applications. Unlike the time and frequency domains, these domains offer un…
