چکیده
Massive MIMO is also known as very-large MIMO (VLMIMO) and large scale antenna systems (LSAS), Hyper MIMO (HMIMO), Full dimension MIMO (FDMIMO) is advance techniques that potentially can offered the large network capacities in multi-user circumstances. With a massive MIMO system, we consider the case where a base station equipped with a large number of antennas elements instantaneously serves the multiple single-antenna users in the same time and frequency source. A massive MIMO system equipped with tens or several hundreds of an antennas which is capable of providing significant improvements to an energy efficiency and robustness of the system. While for the design, performance evaluation and an optimization of massive MIMO wireless systems, realistic channel measurement and their models are indispensable. An emerging the next generation wireless communication systems raises the new requirements on a spectral efficiency and an energy efficiency. Keyboard: 5G, massive MIMO, channel measurement, channel models, energy efficiency.

متن کاملMassive MIMO Performance - TDD Versus FDD: What Do Measurements Say?
Downlink beamforming in Massive MIMO either relies on uplink pilot measurements—exploiting reciprocity and TDD operation, or on the use of a predetermined grid of beams with user equipments reporting their preferred beams, mostly in FDD operation. Massive MIMO in its originally conceived form uses the first strategy, with uplink pilots, whereas there is currently significant commercial interest...

Massive multiple-input multiple-output (MIMO) is seen as an enabling technology to fulfill dramatic improvements in spectral efficiency for 5G deployment in 2020. For massive MIMO systems, the learning loop from early stage prototype design to final stage performance validation, is expected to be slow and ineffective. There is a strong need to evaluate massive MIMO base station (BS) performance...
