| Research Abstract |
In order to achieve one-cell reuse mobile communications systems using block transmission with frequency domain equalization, we have obtained the following results as the key element technologies : 1) theoretical reasoning of the SLNR(Signal to Leakage plus Noise Raito) criterion for the transmit beamforming weight, 2) realization of nearly optimum subcarrier power allocation with 1-bit CSI(Channel State Information) feedback for each subcarrier, 3) asynchronous co-channel interference cancellation scheme for frequency domain equalization systems.
