Abstract

In this paper, a single- and a double-error-correcting receiver of duoquaternary FSK (D-QFSK) are proposed and studied. It is the first time that correlative nonbinary modulations of higher efficiency have been evaluated with nonredundant error correction (NEC) in AWGN and Rayleigh fading environments. Simulations coincide perfectly with the theoretical results derived under AWGN. Single- and double-error correction NEC receivers improve the error rate performance of duoquaternary FSK not only under AWGN but also under destructive Rayleigh fading, making it a good candidate for next generation mobile communications. The improvements reach an order of magnitude for signal to noise ratios exceeding 20 dB
