摘要:
针对部分信道状态信息下的小区间干扰消除问题,通过使用2个独立的随机矢量量化(RVQ)码本分别量化期望信道和干扰信道,首次分析了2个小区MISO有限反馈系统模型下3种波束形成传输策略(特征波束形成、迫零波束形成、最大化信漏噪比)和速率性能,并根据用户在小区中的位置和小区边缘的平均信噪比,研究了基站最优的波束形成传输策略选择.仿真结果表明:当用户噪声受限时,相邻小区基站应选择特征波束形成传输策略;当用户干扰受限时,相邻小区基站应选择最大化信漏噪比传输策略.
Abstract:
The inter-cell interference cancellation schemes were investigated with partial channel state information.The sum-rate performance of three kinds of beamforming transmission strategy(i.e.,eigen-beamforming,zero-forcing beamforming and signal to leakage and noise ratio beamforming)by exploiting two independent random vector quantization codebooks to quantize the desired channel and the interference channel respectively is analyzed.The optimal transmission strategy choice of the base station according to user locations and average cell-edge signal to noise ratio is studied.Simulation results demonstrate that when the user is noise-limited,the neighbor base station will choose eigen-beamforming transmission strategy,and when the user is interference-limited,the neighbor base station will choose signal to leakage and noise ratio beamforming transmission strategy.
