Mobile Communication Systems in the Presence of Fading/Shadowing, Noise and Interference
Petros S. Bithas, Athanasios A. Rontogiannis
In this paper, the effects of interference on composite fading environments, where multipath fading coexists with shadowing, are investigated. Based on some mathematical convenient…
Preamble-based Channel Estimation in OFDM/OQAM Systems: A Review
E. Kofidis, D. Katselis, A. Rontogiannis +1
Filter bank-based multicarrier communications (FBMC) have recently attracted increased interest in both wired (e.g., xDSL, PLC) and wireless (e.g., cognitive radio) applications, d…
Preamble-Based Channel Estimation for CP-OFDM and OFDM/OQAM Systems: A Comparative Study
Dimitris Katselis, Eleftherios Kofidis, Athanasios Rontogiannis +1
In this paper, preamble-based least squares (LS) channel estimation in OFDM systems of the QAM and offset QAM (OQAM) types is considered, in both the frequency and the time domains…
