Adaptive widely linear processing for MIMO systems

open access: yesRevista Tecnologia, 2010
Wireless communication systems using two or more transmit antennas and one or more receiving antennas have emerged in recent years. There are several reasons for this to be occurring, including: the increasing demand for high data rate, high user ...

Phase Noise Effects in Synchronized Wireless Networks for MIMO-OFDM [PDF]

open access: yesMehran University Research Journal of Engineering and Technology, 2014
Channel impairments effects are evaluated by inclusion of phase noise in a synchronization error correction algorithm for MIMO (Multiple Input Multiple Output) OFDM (Orthogonal Frequency Division Multiplexing) systems.

Uniform Quantization for Multi-Antenna Amplify–Quantize–Forward Relay

open access: yesIEEE Access
In this paper, we investigate a multi-antenna amplify-quantize–forward (AQF) relay system, where a half-duplex relay quantizes both the real and imaginary components of amplified received signals, storing them in memory before forwarding them to a

Othogonal Waveform Design for Multiple-Input Multiple-Output (MIMO) Radar

open access: yesOpen Journal of Applied Sciences, 2012
An effective numerical approach is developed for orthogonal waveform design for Multiple-Input Multiple-Output (MIMO) radar. The Doppler shift tolerance is considered in the design cost function. The design results indicate that the Doppler  tolerance of the designed orthogonal waveforms is markedly improved.

Optical multiple input and multiple output (MIMO) in multimode fibre

open access: yes, 2013
Recently, there has been a dramatic increase in the amount of data transmission within short range local area networks (LAN). Multimode fibre (MMF) is widely used in local area networks because of its coupling and alignment along with the low cost of related components. Graded index MMF has become common due to the reduction in pulse spreading; however,
