This work is licensed to IEEE under the Creative Commons Attribution 4.0(CC BY 4.0). The source code is licensed under GPLv2 in https://github.com/sauloqueiroz/lib-ofdmimIn this work, we present an optimal mapper for OFDM with index modulation (OFDM-IM). By optimal we mean the mapper achieves the lowest possible asymptotic computational complexity (CC) when the spectral efficiency (SE) gain over OFDM maximizes. We propose the spectro-computational (SC) analysis to capture the trade-off between CC and SE and to demonstrate that an $N$-subcarrier OFDM-IM mapper must run in exact $\Theta(N)$ time complexity. We show that an OFDM-IM mapper running faster than such complexity cannot reach the maximal SE whereas one running slower nullifies the mapping throughput for arbitrarily large $N$. We demonstrate our theoretical findings by implementing an open-source library that supports all DSP steps to map/demap an N-subcarrier complex frequency-domain OFDM-IM symbol. Our implementation supports different index selector algorithms and is the first to enable the SE maximization while preserving the same time and space asymptotic complexities of the classic OFDM mapper.This work was supported in part by the European Regional Development Fund (FEDER), through the Regional Operational Programme of Lisbon under Grant POR LISBOA 2020, in part by the Competitiveness and Internationalization Operational Programme (COMPETE 2020) of the Portugal 2020 framework [Project 5G with Nr. 024539 under Grant POCI-01-0247-FEDER-024539, and in part by the CONQUEST project - CMU/ECE/0030/2017 Carrier AggregatiON between Licensed Exclusive and Licensed Shared Access FreQUEncy BandS in HeTerogeneous Networks with Small Cells.IEEE2020-02-21info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/106151http://hdl.handle.net/10316/106151https://doi.org/10.1109/ACCESS.2020.2986131eng2169-3536Queiroz, SauloVilela, João P.Monteiro, Edmundoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-04-06T10:20:15Zoai:estudogeral.uc.pt:10316/106151Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:22:36.790261Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
