Reduced Complexity Detection in MIMO Systems with SC-FDE Modulations and Iterative DFE Receivers
Journal of Sensor and Actuator Networks, 2018 This paper considers a Multiple-Input Multiple-Output (MIMO) system with P transmitting and R receiving antennas and different overall noise characteristics on the different receiver antennas (e.g., due to nonlinear effects at the receiver side).

AEU - International Journal of Electronics and Communications, 2018 In this paper, a super-wideband (SWB) printed monopole antenna has been designed and manufactured. The measured frequency band in terms of reflection coefficient is from 3.1 to 20 GHz under a -10 dB criteria, thanks to the inclusion of a taper impedance adapter.

Iterative Receiver Architectures for MIMO-OFDM [PDF]
, 2007 In this paper we propose a turbo-detected multiantenna-multi-carrier receiver scheme. Following the philosophy of the turbo processing, our turbo MIMO-OFDM receiver comprises a succession of detection modules, namely the channel estimator, the space-time
