We investigate channel estimation for long term evolution (LTE) uplink over frequency-selective fading multiple-input multiple-output (MIMO) channels. As the conventional DFT-based channel estimation algorithm used for obtaining the channel impulse response (CIR) in wide band may not be applicable in narrow band of LTE uplink, which results an irreducible error floor, we propose an novel channel estimation...
In this paper, we present a generalized multi-carrier (GMC) transmission technique 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...
