Recent research has shown that code-division multiplex orthogonal frequency-division multiplex (CDM-OFDM) significantly improves the robustness of conventional OFDM against subcarrier fading. In particular, the combination of CDM with multiple transmit antennas has been shown to be very effective in the context of IEEE 802.11n. In this paper another distinctive feature of the forthcoming WLAN standard,...
This paper proposes the use of group-orthogonal frequency diversity combined with space-time block coding (STBC) to improve the performance of IEEE 802.11n wireless networks (WLANs). The extra diversity is achieved by using code-division multiplexing whereby each symbol is transmitted on more than one subcarrier. At reception, following the STBC decoding, a maximum likelihood-based turbo receiver...
This paper introduces a new multicarrier scheme which blends two different methods, code division multiplex (CDM) and cyclic delay diversity (CDD), to deliver a system outperforming the techniques currently in use. The new scheme, termed MC-CDM-CDD, would be a suitable candidate for the next generation of wireless indoor networks. Simulation results using the IEEE 802.11a specifications serve to illustrate...
