emittance control in high power linacs

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...

Adaptive SINR threshold allocation for joint power control and beamforming over wireless networks

AbstmctCochannel interference is one of the main impairments that degrade the performance of a wireless link. Power caintrol and antenna beamforming are two approaches for improving the performance in wireless networks by a p propriately controlling the cochannel interference. Joint o p timal beiimforming and power control scheme has been considered in previous work. It has been shown that the ...

Joint power control and blind beamforming in wireless networks

Traditional power control with beamforming achieves a targeted Signal-to-Interference-Noise-Ratio (SINR) in wireless networks assuming measurement of SINR and direction of arrival (DOA) at the receivers. Blind beamforming is an emerging technique for DOA measurement without consuming extra bandwidth. Here we propose a joint power control and blind beamforming algorithm that reformulates the pow...

Joint Power Control and Blind Beamforming over Wireless Networks: A Cross Layer Approach

Traditional joint power control and beamforming achieve the targeted signal-to-interference-noise ratio (SINR) at the receivers by assuming the knowledge of the measurements of channel parameters and SINR. Blind beamforming is an effective technique for beamforming and channel estimation without the need of training sequences, thus not consuming extra bandwidth. In this paper, we propose a nove...

Joint beamforming and power control in MIMO cognitive radio networks

In this paper, the problem of joint beamforming and power control is studied in the uplink of multiple-input multiple-output (MIMO) cognitive radio networks (CRNs). The objective is maximizing the minimum signal-to-interference-plus-noise ratio (SINR) of the secondary users (SUs). The CRN consists of a cognitive radio-base station (CR-BS) and a number of SUs. The proposed scheme uses genetic al...
