In order to realize the elevation angle estimation for low-altitude targets at a low computational cost, a generalized multiple signal classification (GMUSIC) algorithm based on unitary transform is proposed, i.e., the DU-GMUSIC algorithm. Firstly, the covariance matrix of received data is used to c...

An optimal minimum mean square error successive interference cancellation (OMMSE SIC) scheme for Groupwise space-time block coding (G-STBC) multiple-input multiple-output (MIMO) systems is presented. In such a system, transmit antennas are partitioned into several STBC encoding groups and each group...

As the core algorithm and the most time consuming part of almost every modern network intrusion management system (NIMS), string matching is essential for the inspection of network flows at the line speed. This paper presents a memory and time efficient string matching algorithm specifically designe...

A laser ion source based on laser resonant ionization (RI) at the He-jet outlet was proposed for the ISOL (on-line isotope separator) of HIRFL (Heavy Ion Research Facility in Lanzhou, China) a few years ago^[l]. An off-line test setup was built at Tsinghua University, Beijing. Initial expe...

To mitigate the effects of the previous symbol decision errors of a decision-feedback (DF) equalizer on the current decision, a particle filter (PF) based DF equalizer for frequency selective multiple-input-multiple-output (MIMO) channel is proposed. On the basis of the analyses of DF equalization f...
