Modified DSLM Technique for PAPR Reduction in FBMC System
Allerton Press - Tập 62 - Trang 416-421 - 2019
In the modern age, wireless communication has taken on a wide range of applications in different aspects of a human life. Ever increasing demand for higher data rates led the interest of research in FBMC (Filter Bank Multi-Carrier) as a new transmission system for the next-generation mobile communication system. FBMC is a multicarrier technique which utilized filters at the transmitting and the re...... hiện toàn bộ
Mathematical simulation of characteristics of angular coordinate estimates of radar targets in the vicinity of interface between two media
Allerton Press - Tập 50 - Trang 35-43 - 2007
The calculations, used for investigating the characteristics of measurement of radar targets’ angular coordinates near the interface between two media, are based on mathematical models set up as superposition (in the observation point) of two waves reflected from the object: the direct wave and the wave reflected by the surface of the interface between two media. These mathematical models are show...... hiện toàn bộ
Robust Scene-Based Digital Video Watermarking Scheme Using Level-3 DWT: Approach, Evaluation, and Experimentation
Allerton Press - Tập 61 - Trang 1-12 - 2018
This paper presents a robust digital video-watermarking system for copyright and copy protection. The proposed method applies the combination of discrete wavelet transform (DWT) and scene-change-detector. For better understanding, this approach can be presented in the form of four stages. The first stage is finding the frame where the watermark is to be inserted. The analysis of watermarking using...... hiện toàn bộ

Identification and analysis of interference effects of GSM base stations
Allerton Press - Tập 52 - Trang 55-62 - 2009
An algorithm has been developed and implemented for receiving the broadcast data of base stations of GSM networks that allows us to obtain their identification parameters and carry out the analysis of mutual interference effects. Acase study of the analysis of frequency channels in the 900 MHz band at the fixed point of industrial center was also presented.
Dual-band devices based on coupled-stripline section with cross-symmetrical loads
Allerton Press - Tập 57 - Trang 531-541 - 2015
An equivalent representation of a circuit formed by coupled lines section with cross-symmetrical loads and additional reactive elements is suggested in the form of partial one-port networks with in-phase or antiphase excitation. Analytical relations for the electrical parameters calculation of elements of the circuit, which enables one to implement devices with dual-band operation mode, have been ...... hiện toàn bộ
Characteristics of estimating the amplitude of ultrawideband quasi-radio signal
Allerton Press - Tập 53 - Trang 241-250 - 2010
Thesynthesis and analysis of the maximum likelihood algorithm for estimating the amplitude of ultrawideband quasi-radio signal with unknown amplitude and phase have been performed. The duration of the specified signal can amount to several periods or a fraction of the period of harmonic oscillation. The characteristics of the classical maximum likelihood estimate of the amplitude of a narrow-band ...... hiện toàn bộ
Phân rã mô hình đa thức từng đoạn của bộ tiền biến dạng cho bộ khuếch đại công suất Dịch bởi AI
Allerton Press - Tập 58 - Trang 90-95 - 2015
Việc phân rã mô hình đa thức từng đoạn của bộ tiền biến dạng đã được thực hiện với sự xem xét đến động lực thay đổi của độ lớn vùng bao quát phức cho tín hiệu, tín hiệu này được chuyển đổi bởi một bộ khuếch đại. Mô hình phân rã cung cấp độ chính xác cao hơn trong việc bù đắp cho các biến dạng phi tuyến cho tín hiệu trong bộ khuếch đại so với mô hình đa thức từng đoạn của bộ tiền biến dạng. Phân tí...... hiện toàn bộ
