Enhanced LAA for Unlicensed LTE Deployment Based on TXOP Contention

Coexistence of Wi-fi and Laa-lte in Unlicensed Spectrum

ACKNOWLEDGEMENTS First and foremost, I would like to especially thank my mother, father and families, without whose guidance and support I would not be here. Besides, I would like to present my sincere gratitude to my supervisor, Dr Raghu-pathy Sivakumar. Under his guidance, I got valuable advice and encouragements. I joined in GNAN research group without much research experience. Because of Si...

U-LTE: Unlicensed Spectrum Utilization of LTE

Adaptive Video Streaming over LTE Unlicensed

In this paper we consider the problem of adaptive video streaming over an LTE-A network that utilizes Licensed Assisted Access (LAA) which is an instance of LTE Unlicensed. With LTE Unlicensed users of the LTE-A network opportunistically access radio resources from unlicensed and licensed carriers through Carrier Aggregation (CA). Our objective is to select the highest possible video quality fo...

Device-to-device (D2D) Meets LTE-Unlicensed

In this article, we look into how the LTE network can efficiently evolve to cater for new data services by utilizing direct communications between mobile devices and extending the direct transmissions to the unlicensed bands, i.e., device-to-device (D2D) communications in conjunction with LTE-Unlicensed. In doing so, it provides an opportunity to solve the main challenge of mutual interference ...

application of upfc based on svpwm for power quality improvement

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...
