Combining Switched TMAs and FDAs to Synthesize Dot-Shaped Beampatterns
(Institute of Electrical and Electronics Engineers, 2021)
[Abstract]: The application of frequency offsets to the elements of a conventional phased array with variable phase shifters (VPSs) leads to frequency diverse arrays (FDAs) with the ability to provide range-angle spatial ...
Reply to “Comments on ‘Combining Switched TMAs and FDAs to Synthesize Dot-Shaped Beampatterns”’
(Institute of Electrical and Electronics Engineers, 2021)
[Abstract]: It is noted that the main innovation contained lies in the consideration of frequency diverse arrays (FDAs) feeding networks made up of time-modulating switches (hence, the term TMA-FDA) instead of phase shifters. ...
Broadband Access in Complex Environments: LTE on Railway
(Institute of Electronics, Information and Communication Engineers, 2014)
[Abstract]: This paper assesses the main challenges associated with the propagation and channel modeling of broadband radio systems in a complex environment of high speed and metropolitan railways. These challenges comprise ...
Experimental evaluation of the WiMAX downlink physical layer in high-mobility scenarios
(SpringerOpen & European Association for Signal Processing, 2015)
[Abstract]: The experimental evaluation of the WiMAX downlink physical layer in high-mobility scenarios is extremely difficult to carry out because it requires the realization of measurement campaigns with expensive ...
A comparative study of STBC transmissions at 2.4 GHz over indoor channels using a 2 × 2 MIMO testbed
(Hindawi, 2008)
[Abstract]: In this paper we employ a 2 × 2 Multiple-Input Multiple-Output (MIMO) hardware platform to evaluate, in realistic indoor scenarios, the performance of different space-time block coded (STBC) transmissions at ...
Blind channel identification in Alamouti coded systems: a comparative study of eigendecomposition methods in indoor transmissions at 2.4 GHz
(Wiley, 2008)
[Abstract]: This paper focuses on blind channel estimation in Alamouti coded systems with one receiving antenna working in indoor scenarios where the flat fading assumption is reasonable. A comparative study of several ...
