| 英文摘要 | In high mobility orthogonal-frequency division multiplexing (ofdm) systems, time-varying channels destroy the orthogonality among subcarriers and the resultant intercarrier interference (ici) degrades the receiver performance. to obtain an effective balance of performance and complexity at the receiver, we proposed to split the channel frequency response (cfr) matrix into a sequence of submatrices rather than using the whole cfr matrix. then, we derived a soft information based sequentially iterative minimum mean square error (mmse) equalizer, which fully exploits the ici distribution property. analysis and simulations demonstrate that this scheme provides a flexible and controllable approach to trade off performance for complexity, since it can be simply done by choosing different size of the parameter q. meanwhile, superior ability of the ici suppression is maintained when compared with previous equalization schemes. this feature indicates its potential application for future wireless communications. |
