Recommended by Huaiyu Dai Design and implementation of a highly optimized MIMO (multiple-input multiple-output) detector requires cooptimization of the algorithm with the underlying hardware architecture. Special attention must be paid to application requirements such as throughput, latency, and resource constraints. In this work, we focus on a highly(More)

— This paper introduces a super-orthogonal space-time block coding scheme. The code construction is based on the expansion of orthogonal block code via a unitary matrix transformation. By expanding the orthogonal block code, both the code rate can be increased and the performance improved in terms of E b /N 0 , with a moderate increase of the receiver(More)
This paper describes a family of knowledge representation problems, whose intuitive solutions require reasoning about defaults, the effects of actions, and quantitative probabilities. We describe an extension of the probabilistic logic language P-log (Baral & Gelfond & Rushton 2004), which uses " consistency restoring rules " to tackle the problems(More)
This paper introduces an open access wideband multi-antenna wireless testbed. The testbed is configured as a four transmit antenna by four receive antenna system based on software defined radio techonology. It operates in the 2.4GHz ISM band and supports an RF bandwidth compatible to IEEE 802.11a/g standard. A robotic positioning system has been developed(More)

Absfracl-Multiple antenna radios are recently the subject of much research due to the significant improvements they offer in throughput and reliability in rireless communications. Research in the field of space-time coding has led to the design of modulation techniques offering improved performance. Their performance, although promising in simulations,(More)
This paper reports on a highly optimized 4x4 MMSE detector implementation. The work resulted in a real-time FPGA based implementation on a Xilinx Virtex-II 6000 part. It utilizes 8,513 logic slices, 64 multipliers, and 23 Block RAMs (less than 30% of the overall resources of this part). The design delivers over 420 Mbps sustained throughput, with a small(More)
Highly active antiretroviral therapy (HAART) has transformed HIV-1 infection from a deadly disease to a manageable chronic illness, albeit does not provide a cure. The recently developed genome editing system called CRISPR/Cas9 offers a new tool to inactivate the integrated latent HIV-1 DNA and may serve as a new avenue toward cure. We tested 10 sites in(More)
Emerging telemedicine programs offer potential low-cost solutions to the management of chronic disease. We sought to evaluate the clinical effectiveness and cost effectiveness of telemedicine approaches on glycemic control in patients with type 2 diabetes mellitus. Using terms related to type 2 diabetes and telemedicine, MEDLINE, Cochrane, EMBASE, and(More)
A real time, 2 Mbps to 200 Mbps portable radio unit with MIMO and sensing capability which exposes all the PHY parameters to the higher layers will help advance experimental cognitive radio (CR), and wireless networking research. Collaboration between Silvus Communication Systems and the UCLA WISR group has resulted in the first generation radio(More)
