Multiport antenna performance analysis from ray-traced channels for small cells

摘要: The evaluation of multi-element antenna (MEA) performance in urban environments is particularly important for the planning and design reliable, spectrally efficient systems. To date, MIMO communication using large dimensions has not been implemented commercial But potential capacity much more significant when become large. hold-up just shortfall understanding how to deploy large-dimension MIMO, but also There no widely agreed method evaluating MEAs used by communications. Even a well-established configuration, such as small scale systems already used, remains limited. often defers OTA tests artificial environmental conditions. real-world unclear, so care must be taken optimization. In this paper, we discuss incorporation some physical modeling propagation environment MEA typical wireless channel. A ray-optic applicable any 3D environment, number antennas with arbitrary patterns. sense it offers practical approach being able change all software. illustrated an slot cube (12 antennas) operating specific namely downtown Ottawa.
