Study on Transmission Technology for Millimeter-wave Vehicle Area Network

为了实现毫米波车载区域网络（VAN）传输技术，建立了一种车载毫米波信道模型。通过测量毫米波在汽车中的传播特性，结果表明，无需复杂的均衡器，Omni天线可以实现6-7 ns的最大延迟传播。波束形成天线性能的可行进步将使车内最大延迟传播减少到1-2纳秒。这一结果证明，毫米波车载区域网络可以通过使用一个基本的单载波调制解调器和简单的rake接收器来实现；不需要均衡。

A millimeter-wave channel model in the car has been developed to realize millimeter-wave vehicle area network(VAN)transmission technologies. By measuring the millimeter-wave propagation characteristics in the car, the results show the maximum delay spread of 6-7 ns can be achieved with Omni antennas without complicated equalizers. Feasible advances in beam forming antenna performance will reduce the maximum delay spread inside the car to only 1-2 ns. This result proves that millimeter-wave vehicle area networks can be achieved by employing a basic single carrier modem with simple rake receivers ; no equalization is needed.
