With the ever growing surveillance data, it is important and urgent to effectively and efficiently manage and utilize the huge amount of surveillance video repositories. In order to browse the video data quickly and make full use of the surveillance video data, we propose a fully automatic and computationally efficient framework for analysis and(More)
The great development of general-purpose processor technology makes the GPP possess the efficiently massive data processing abilities. In the solution(s) of 3GPP LTE system based on GPP platform, Turbo decoding algorithms play a vital role for high decoding complexity. This paper presents the design and implementation of SIMD technique based parallel turbo(More)
The adaptive beamforming algorithm-minimum variance distortionless response (MVDR) has been studied based on the electronically steerable parasitic array radiator (ESPAR) antenna. The ESPAR antenna uses a single radio-frequency (RF) front end, and its beamforming is achieved by adjusting reactance loads of parasitic elements coupled to the central active(More)
Recently, a class of “Blind Interference Alignment (BIA)” techniques has been proposed in [3] and [4], which allows interference alignment to be achieved without knowledge of channel coefficients at the transmitter. In [4], the key to realizing the BIA for multi-user (MU) multiple-output-single-input (MISO) broadcast channel (BC) is the use of(More)
Spectrum sensing is one of the key challenges in the cognitive radio network. Primary user signal must be detected reliably in the low signal-to-noise ratio (SNR) regime and in multipath fading environments. This paper analyzes effects of time-variant multipath Rayleigh fading channel on cyclostationary characteristics and derives the relationship between(More)
A web-based research information system was designed to enable our research team to efficiently measure health related quality of life among frail older adults in a variety of health care settings (home care, nursing homes, assisted living, PACE). The structure, process, and outcome data is collected using laptop computers and downloaded to a SQL database.(More)
Recently, a technique entitled “Blind Interference Alignment (BIA)” was proposed, which allows interference to be aligned within a reduced subspace without knowledge of the channel state information at the transmitter. The key to realizing the BIA scheme is the use of a receive antenna that is capable of switching among multiple channel-states(More)
