Multiple Signal Representation for ICI reduction in Time-varing OFDM

摘要：

　　In this paper two multiple signal representation transceiver design schemes called selected mapping schemes (SLM) and partial transmit sequence (PTS) are utilized for orthogonal frequency division multiplexing (OFDM) in linear time-varying (LTV) channels.In order to reduce inter-carrier interference (ICI) due to the time-varying of channel,we introduce the peak interference-to-carrier-ratio (PICR) as a measurement for the resulting inter-carrier interference,thus randomly generate a serial number of transmit sequence and choose the best sequence that can make the PICR minimal to adjust transmit data.With these mentioned methods,we show a low-complexity one-tap equalization could also obtain satisfactory performance.These schemes are analyzed theoretically.Simulation shows the performance and proves that the proposed method can suppress ICI effectively.
