Kalyanasundaram, P. (author), Huang, L. (author), Dolmans, G. (author), Imamura, K. (author)Super-regenerative receiver is one of the potential candidates to achieve ultra low power wireless communication in body area network (BAN). The main limitations of the super-regenerative receiver include the difficulty in choosing a good quench waveform to optimize its sensitivity and selectivity, and its significantly degraded performance in...conference paper 2012

Weber, J.H. (author), Schouhamer Immink, K.A. (author), Ferreira, H.C. (author)Knuth's celebrated balancing method consists of inverting the first z bits in a binary information sequence, such that the resulting sequence has as many ones as zeroes, and communicating the index z to the receiver through a short balanced prefix. In the proposed method, Knuth's scheme is extended with error-correcting capabilities, where it is...conference paper 2011

Amaldoss, S.E. (author), Yarovoy, A. (author)The effectiveness of a cavity for dual-band patch radiator with a frequency ratio of 1.65:1 is analysed. The use of cavities can help in maintaining impedance matching, reducing the levels of mutual coupling between the elements as well as in containing the surface waves, aspects vital to array performance. Results demonstrate that with the use...conference paper 2011

Le Chevalier, F. (author), Krasnov, O.A. (author), Deudon, F. (author), Bidon, S. (author)Wideband (high range resolution) radars have been proposed [7] as high performance systems for detection of small targets in adverse environments, due to their small resolution cells and non-ambiguity in range and velocity (velocity ambiguity removed by the measurement of the range migration of the target during the pulse train duration)....conference paper 2011

Babur, G. (author), Wang, Z. (author), Krasnov, O.A. (author), Ligthart, L.P. (author)This paper presents design and practical implementation of the method for cross-channel interference suppression in polarimetric LFM-CW radar with dual-orthogonal sounding signals. Simultaneously transmitted and received signals have limited orthogonality, what results in the interfering signals in the processing channels of the radar receiver....conference paper 2010

Tadema, J. (author), Koeners, J. (author), Theunissen, E. (author)In the past fifteen years, several research programs have demonstrated potential advantages of synthetic vision technology for manned aviation. More recently, some research programs have focused on integrating synthetic vision technology into control stations for remotely controlled aircraft. The contribution of synthetic vision can be divided...conference paper 2006
