This paper presents the first systematic study on co-scheduling independent jobs on integrated CPU-GPU systems with power caps considered. It reveals the performance degradations caused by the co-run contentions at the levels of both memory and power. It then examines the problem of using job co-scheduling to alleviate the degradations in this less understood scenario. It offers several algorithms...
Based on the high gain beam forming and overall spatial beam scanning properties of Luneburg lens, a phased monopole array mounted on the surface of a Luneburg lens is proposed. With controlled distributions of excitation amplitude and phase on four adjacent monopole elements, this monopole array can form continuously scanned beams instead of the conventional discrete beams. To demonstrate this feature,...
We consider an OFDM-based multi-relay network in this letter, where a certain subcarrier pair can be forwarded by the source node and multiple relays to provide space diversity. A joint optimization scheme for power allocation (PA) and subcarrier pairing (SP) is proposed to maximize the total end-to-end transmission rate under a total power constraint. The optimization problem is simplified by introducing...
ML-DFE algorithm is known as the combination of the ZF-DFE algorithm and ML algorithm. In this paper, OSIC-ML is proposed as the simplified algorithm of the ML-DFE, by exchanging the executive order of OSIC and ML, using simple matrix operations to replace the method of through QR decomposition to find a unitary matrix for matrix resolution. ML-DFE algorithm decreases complexity of the matrix operations,...
