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

为了实现基于频域均衡的分块传输单小区复用移动通信系统，我们获得了以下作为关键要素的技术成果：1)理论推导了发射波束形成权重的SLNR准则；2)利用每个子载波1位信道状态信息反馈实现了近乎最优的子载波功率分配；3)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.
