6. High-End Performance with Low-End Hardware : Analysis of Massive MIMO Base Station Transceivers
Abstract : Massive MIMO (multiple-input–multiple-output) is a multi-antenna technology for cellular wireless communication, where the base station uses a large number of individually controllable antennas to multiplex users spatially. This technology can provide a high spectral efficiency. READ MORE
