An iterative design of minimum mean square error decision feedback equalizer (MMSE-DFE) to suppress the intercarrier interference (ICI) of orthogonal frequency division multiplexing systems in the time-variant channels is analyzed in this paper. The channel is assumed to vary in a linear fashion within a frame. The error power transfer is investigated in parallel with the equalizing process, showing...
This paper presents a broadband multimedia transmission system for the ultra-high-speed mobile application. Based on the time-domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) system, training sequences in frame headers are regarded as samples of time-varying channel parameters under the fast-varying channel, instead of assuming that the channel impulse response remains constant...
