OPTIMAL BLOCK BASED DMT TRANSCEIVERS
OPTIMAL BLOCK BASED DMT TRANSCEIVERS J.P CANCES, G.R MOHAMMAD-KHANI,V. MEGHDADI (ENSIL University of LIMOGES, cances@ensil.unilim.fr) Abstract: The design of optimal DMT transceivers for distorted channel with colored noise has been of great interest. Of particular interest is the class of block based DMT (BDMT), where the transmitter and the receiver consist of constant matrices. For a given chan
Space-Time Block Coded Multi-Carrier CDMA in Downlink Rayleigh Fading Channel
Space-Time Block Coded Multi-Carrier CDMA in Downlink Rayleigh Fading Channel M. Hajian, G. Op de Beeck, L. P. Ligthart, Senior member of IEEE Abstract-- This paper studies the performance of multicarrier CDMA in combination with space-time block coding. The system uses different equalization techniques and different antenna configurations. The performance of the system is analyzed by analytic der
