蜂窝系统中分布式空域基站协作的仿真研究

对分布式空域基站协作进行了分析仿真，重点对两小区场景和三小区场景采用最大化层虚拟信干噪比算法的预编码技术进行了仿真验证，并与采用最大化虚拟信干噪比算法的预编码技术进行了比对。仿真结果表明通过分布式的基站协作预编码算法，可以有效地抑制小区间干扰，提高系统的性能；结果还表明层虚拟信干噪比算法比虚拟信干噪比算法有更好的性能，增加天线数量也可以提高系统的性能。

Simulation of Distributed Base-Station Collaboration in Cellular System

A solution for distributed base-station collaboration is simulated, with focus on the simulation ofpreceding technologies based on maximum-layer virtual signal-to-interference plus noise ratio in two-cell and three-cell scenarios, and the comparison of preceding technology with the technology based on virtual signal-to- interference plus noise ratio also done. The simulation result shows that the solution for distribu- ted base-station collaboration can effectively suppress inter-cell interference and improve system perform- ance, and this result also indicates that the layer virtual SINR algorithm is better than virtual SINR algo- rithm,while the system loerformance can be improved by increasing the number of antennas.
