Based on the space alternating generalized expectation maximization (SAGE) technique, and the ordered serial interference cancellation (OSIC) algorithm, an improved low-complexity inter-carrier interference (ICI) mitigation scheme, named SAGE-OSIC, is proposed for high mobile orthogonal frequency division multiplexing (OFDM) systems, where the subcarriers(More)
—The Channel State Information (CSI) plays a significant role in wireless Relay Selection (RS) systems. Due to the time variation of channels, the CSI in the data transmission phase may differ (i.e., is outdated) from that in the relay selection phase. Addressing this issue, the Decode-andForward (DF) Two-Way Relaying (TWR) network is considered, and the(More)
