One-cell reuse mobile communications systems using block transmission with frequency domain equalization

为了实现使用具有频域均衡的块传输的单小区复用移动的通信系统，我们获得了以下结果作为关键要素技术：1）SLNR的理论推理用于发射波束成形权重的（信号与泄漏加噪声的比率）准则，2）利用1比特CSI实现接近最优的子载波功率分配（信道状态信息）反馈，3）用于频域均衡系统的异步同信道干扰消除方案。

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.
