为了提高毫米波无线个域网(mm-wave WPAN)的空间复用增益,提出了一种干扰感知波束成型机制(IBF),进而提出了一种基于物理干扰模型的最大共存可能(MCP)算法.利用IBF所得干扰信息,并结合物理干扰模型确定的链路共存条件,MCP算法可准确有效地寻找共存链路集,达到增大空间复用增益的目的.仿真结果表明,该算法与基于协议干扰模型的最大扇区差算法(MSDN)和基于物理干扰模型的盲选算法相比,具有更高的复用增益,且其优势会随着扇区数、节点数的增加更为明显.
In order to improve the spatial multiplexing gain of mm-wave WPAN, an interference-aware beamforming mechanism (IBF) is proposed, and then a Maximum Coexistence (MCP) algorithm based on the physical interference model By using the interference information obtained from IBF and combining with the link coexistence conditions determined by the physical interference model, the MCP algorithm can find the coexistence link set accurately and efficiently to achieve the purpose of increasing the spatial multiplexing gain.The simulation results show that this algorithm is compatible with the protocol Compared with the blind selection algorithm based on the physical interference model, the maximum sector difference algorithm (MSDN) of the interference model has a higher multiplexing gain, and its advantage is more obvious with the increase of the number of sectors and nodes.
