Abstract :
We derive a layered space-time scheme for multi-antenna orthogonal frequency-division multiplexed transmissions over frequency-selective channels. Compared with existing alternatives, the proposed scheme can attain very high spectral efficiency as well as improved performance. Enhanced diversity gains document its superior performance that is also tested by simulation.
