A generalized multi-carrier (GMC) wireless transmission scheme is presented in multi-input and multi-output (MIMO) channel environments for beyond 3G mobile communications.Several key techniques including the design and implementation of the GMC synthesis/analysis system
adaptive double-cyclic timeslot structure
pilot design and channel estimation
and iterative detection/decoding are briefly discussed.Link-level simulation results in Rayleigh fading MIMO channels are provided.
