Signal-Code Constructions Based on Index Modulation Aided OFDM and Space-Time Block Coding for Frequency-Selective and Time Varying Wireless Communication Channels
Abstract:New spectrally and energy-efficient signal-code construction (SCC) based on Index Modulation aided OFDM and Space-Time Block Coding, and also its noise-immune version in phase instability conditions with Inter-Channel Interference compensation operator, built intoAlamouti's coder structure, and increasing signals frequency diversity operator (Walsh-Hadamard) are proposed. In a complicated interference environment, first of all, under the influence of electronic suppression means, such methods increase simultan… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
