Massive MIMO test-bed design for next-generation long term evolution (LTE) mobile systems in the frequency division duplex (FDD) mode

A massive MIMO test-bed under design is introduced as the pilot for next-generation long term evolution (LTE) mobile systems in the frequency division duplex (FDD) mode. In the design stage, computer simulations are performed and in a given conditions the results demonstrate that the test-bed algorithms possibly fulfill the capacity requirements of the fifth generation cellular system, which is one thousand times of that of the legacy LTE system. However, the complexity of the test-bed is not significantly increased with the adoption of new concepts like user grouping and beamforming, which enables the base station (BS) to use both smaller numbers of transmit pilot patterns and smaller amounts of channel state information feedback.
