Multiple-Input Multiple-Output (MIMO) Communication System Using Reconfigurable Antennas
Decreases the required size of antenna arrays for space-sensitive devicesReduces cost of MIMO implementation by using less radio frequency (RF) hardware on both transmitter and receiver sidesProvides superior reliability and efficiency when compared to traditional MIMO systems
Implementation of reconfigurable antennas into MIMO communications systems where small form factor, low power consumption, and hardware cost are important
MIMO communications systems are capable of providing high-speed, high-quality wireless communications. A traditional MIMO system requires multiple physical antennas, posing a major challenge to the adoption of such systems in mobile devices. Reconfigurable antennas are a promising way to eliminate the need for multiple antennas, by using a single antenna capable of altering its radiation pattern, operating frequency and/or polarization characteristics. State of the art MIMO systems have only been able to implement reconfigurable antennas on the receiver side. UCI inventors have reduced the cost, power consumption, and implementation complexity of current MIMO systems by developing a general case which employs the reconfigurable antennas at both the transmitter and receiver. By employing a state-switching scheme at the transmitter and a state-selection scheme at the receiver, efficiency and performance of the MIMO system are enhanced. Average signal to noise ratio (SNR) is enhanced while achieving maximum diversity gains, an improvement upon wireless communication in existing and next generation systems.
