UE Calibration in MIMO Systems
2012 IEEE Vehicular Technology Conference (VTC Fall), 2012The paper describes an antenna path calibration method for (Multiple Input Multiple Output) MIMO systems. In a MIMO system, the RF components used at each transmit/receive antenna path, i.e., uplink versus downlink, do not exhibit similar phase and amplitude responses.

Chaotic Communications in MIMO Systems
2007In wireless communications, chaotic communications have been a field of interest due to its low complexity in hardware implementation and low power consumption in chaotic signal generation. Among the modulation schemes using the chaotic signal, Differential Chaos Shift Keying (DCSK) is a robust noncoherent technique.

Broadband MIMO antennas for MIMO radar systems
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013Methods of reducing both electric and magnetic field coupling for enhancing the isolation in broadband MIMO antenna system is presented. The proposed MIMO antenna consists of two coplanar waveguide (CPW) fed self-complementary antennas (SCAs) and a U-shaped slot is etched on the ground plane.

Overlapped-MIMO Radar and MIMO Cellular System
2017In this chapter, we explore a collocated overlapped multiple-input multiple-output (Overlapped-MIMO) radar waveform design, which is combined with an algorithm to share spectrum through null space projection (NSP) for the coexistence of radar and communications system.
