【摘要】 这里提出了1种新的基站空域协作干扰抑制方案,该方案根据用户受到干扰的不同情况,动态地对相邻小区基站进行划分成簇。同时对所提出的方案在不同预编码算法和不同发送天线数目的条件下用Matlab软件进行仿真验证,其中,预编码算法的选择需要根据系统性能需求和实现的复杂度进行权衡。仿真结果表明所提出的动态协作簇小区间干扰抑制方案可以有效地抑制小区间干扰,同时大大地提高系统的性能。更多还原

【Abstract】 A new basestation collaborative solution in space domain is proposed,which dynamically divides the adjacent cells of the basestations into clusters according to the interferences imposed on users.The proposed solution is simulated with different pre-coding algorithms and different number of transmit antennas.The pre-coding algorithms are chosen in consideration of the system performance and the complexity of the algorithm.The simulation results show that the dynamic collaborative cluster inter-cell interference suppression solution could effectively improve system performance.更多还原
