On behalf of the Organizing Committee, it is our great pleasure to invite you to attend the 2012 IEEE International Conference on Signal Processing, Communications and Computing, to be held in Hong Kong on August 12–15, 2012 at The Hong Kong Polytechnic University.
Welcome to the 2012 International Conference on Signal Processing, Communications and Computing (ICSPCC), being held on August 12–15, 2012 in Hong Kong. This conference is intended to be a platform of academic exchange for researchers in signal processing, multimedia, telecommunications, computer systems and computing. Particularly, we hope to create more opportunities of interaction among young colleagues...
Sub-arrayed multiple-input multiple-output (MIMO) radar is a new architecture of MIMO radar, which can exploit jointly the benefits of the coherent processing gain and waveform diversity, and has received extensive attention of researchers. An approach to synthesize the desired transmit beampattern for sub-arrayed MIMO radar is proposed in this paper. The essence of this approach is that the transmit...
A novel radar target recognition method based on physical-statistical model is proposed, which uses sequences of full-polarization high resolution radar range-profiles (HRRP). The HRRP of target is modeled as a Middleton's Class A non-Gaussian distribution through a physical consideration. It is found that the model parameters describe the scattering physical characteristics of radar target and can...
Current passive reverberation methods have certain limitations when applied into practice, which would null boundary reverberation and target echo simultaneously. As a solution, a passive reverberation nulling method based on reverberation subspace estimation for target enhancement is proposed in this paper. In this method, the reverberation subspace for target range cell is not obtained directly...
Phased-multiple-input multiple-output (MIMO) radar enjoys the advantages of MIMO radar in diversity gain without sacrificing the main advantage of phased-array radar in coherent transmit gain. However, a limitation of the phased-MIMO radar is that the beam steering is fixed in an angle for all the ranges. This limits the system performance to mitigate non-desirable range-dependent interferences. To...
In the high frequency (HF) band, a continuum bandwidth for achieving the desired range resolution is difficult to find. Besides, the power which returns from ship targets is usually lower than the levels of sea clutters at higher sea states. Therefore, it is difficult to distinguish desired targets by conventional approaches. In this paper, a multi-frequency frequency modulated continuous wave (FMCW)...
Microstrip antennas are excited for radiation modes using different techniques which lead to best impedance matching between the feed line and the patch. This paper describes two techniques which use microstrip line and also coaxial line as feed line for a rectangular patch. The analysis was carried out using ANSOFT High frequency structure simulator (HFSS). By changing the position of the feed point...
In this paper, a flat-top beam pattern is generated through time modulation of linear array. Three parameters; side lobe level (SLL), ripple (R) and transition width (T) related are obtained as −30.2dB, 0.1dB and 6.4° respectively. To simplify the complexity of the feeding network, only two states of static phase shift (0, π) is considered. The maximum side band radiation level of the first two sidebands...
Smart antenna involves array processing to manipulate the signals induced on various antenna elements to accomplish beam steering and improve interference rejection. To improve directivity a shaped dielectric lens is used to further collimate the rays in a specified direction and help reduce interference. Direction Of Arrival (DOA) estimation algorithms specifically Multiple SIgnal Classification...
In this paper, a minimum mean square error - bidirectional successive detection (MMSE-BSD) technique is proposed to mitigate the effects of interferences caused by time difference of arrivals (TDoAs) in wireless mesh networks (WMNs) based on orthogonal frequency division multiple access (OFDMA). The proposed BSD technique can successfully reduce the error propagation phenomenon in successive detection...
