Abstract

Multiple-input, multiple-output (MIMO) systems provide several benefits over single-input, single- output (SISO) air interfaces regarding spectral efficiency and reliability. An integrated wireless radio for short-range communication is developed that performs MIMO signal processing already in the analog radio frequency (RF) front-end. This concept allows using synergies in components and subsystems of the air interface leading to reduced system size, costs, and power consumption. The transceiver is developed in such networks with data speeds up to the Gb/s range in the next years demanding for better spectral efficiencies in existing and emerging wireless radios [1]. To achieve this goal, evolutionary and revolutionary approaches are currently explored and developed for shortrange communication
