Design of an EM-based Receiver Using Markov Chain Monte Carlo Method for OFDM Systems in Doubly Selective Channels
碩士 === 國立交通大學 === 電信工程系所 === 97 === Doubly selective (fading) channels cause the inter-carrier interference (ICI) problem and thus degrade the system performance. In order to estimate the ICI effect made by the spreading energy of adjacent subcarriers, we propose an expectation-maximization (EM)-bas...
