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 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)
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)
A real time, 2 Mbps to 150 Mbps portable SDR 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. The current SDR implements a slight variant of the 802.11n draft specification, with the entire baseband implemented on a single… (More)
In this paper, the exact value for the norm of directional derivatives, of all orders, for symmetric tensor powers of operators on finite dimensional vector spaces is presented. Using this result, an upper bound for the norm of all directional derivatives of immanants is obtained.
Agriculture data is highly broadened in terms of irrigation sources, climate, soil and inputs like fertilizers and pesticides. For sustainable growth of agriculture, these resources need to be monitored, analyzed and allocated optimally. Data Mining techniques may be used in agricultural data for mining the association rules among various inputs and outputs… (More)
