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 optimized matrix inversion free(More)
This paper reports on a highly optimized 4×4 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(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)
Multiple antenna systems are of significant interest to the wireless communications community because of the increase they offer in throughput and reliability [1–3]. While theory and simulations typically show the corresponding gains under ideal conditions, hardware platforms and testbeds are essential in validating these gains in real channels and in the(More)
BACKGROUND Organizational models in the intensive care unit (ICU) have classically been described as either closed or open, depending on the presence or absence of a dedicated ICU team. Although a closed model has been shown to improve patient outcomes in medical and surgical ICUs, the merits of various care models have not been previously explored in the(More)
