We present a complex regression SVM formulation specifically adapted to a pilots-based OFDM signal. This novel proposal provides a simpler scheme than an SVM classification method. The feasibility of our approach is substantiated by computer simulation results obtained for IEEE 802.16 broadband fixed wireless channel models. These experiments allow to scrutinize the performance of the OFDM-SVM system and the suitability of the -Huber cost function, in the presence of non-Gaussian impulse noise interfering with OFDM pilot symbols.enAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Telecomunicacionesinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess3325 Tecnología de las Telecomunicaciones
