Correlations of the topological charge Q, the electric current J and the magnetic current J in SU(2) lattice gauge theory in the Maximal Abelian projection are investigated. It occurs that the correlator ≪ QJJ ≫ is nonzero for a wide range of values of the bare charge. It is shown that: (i) the abelian monopoles in the Maximal Abelian projection are dyons which carry fluctuating electric charge...

John T. Shen, MEMBER SPIE Northwestern University Department of Electrical and Computer Engineering Evanston, Illinois 60208 Abstract. For practical pattern recognition and tracking systems, it is often useful to have a high-speed random access memory (RAM) that complements a holographic correlator. Recently, we have demonstrated a super-parallel holographic correlator, which uniquely identifie...

We calculate wide distance connected correlators in non-gaussian orthogonal , unitary and symplectic random matrix ensembles by solving the loop equation in the 1/N-expansion. The multi-level correlator is shown to be universal in large N limit. We show the algorithm to obtain the connected correlator to an arbitrary order in the 1/N-expansion.

David Garrett and Mircea Stan [email protected], [email protected] University of Virginia, Department of Electrical Engineering AbstractDirect Sequence Spread Spectrum (DSSS) transmissions require a despreading stage within the standard receiver block to recover the spread spectrum signal. For long spread spectrum codes, the correlation block can be a large portion of the receiver size, he...

4 A 4 1 0 ~ 0 . 8 = 8 ~ ~ .id 1 1.6 + 2 x 3.2 = 8 p Abstract Timing synchronization for IEEE 802.1 l a KLANs requires using a correlator to correlate the received signal with a known waveform. Straightforward implementation of this correlator results in the need to perform 320 million complex multiplications per second. This signijicant requirement can be eliminated by using multiplierless corr...

A digital high-speed cross-correlator (HSCC) has been developed for use in a microwave polarimetry instrument. The HSCC incorporates radiation tolerant circuit design and an ultra-low power CMOS process. In order to meet the very high input data requirement of 500 megasamples per second the correlator architecture was partitioned into different sections, each with its own trade-off requirements...

Building on the base of existing telescopes Event Horizon Telescope (EHT) and ALMA, next-generation EHT (ngEHT) aspires to deploy ?10 more stations. The ngEHT targets an angular resolution ?15 microarcseconds. This is achieved using Very Long Baseline Interferometry (VLBI) at shortest radio wavelengths ?1 mm. Submillimeter Array (SMA) both a standalone interferometer station will conduct observ...

Optimal digital data detection for a linear Gaussian (fading) channel is considered in the context of the estimator-correlator and recent recursive structures for sequence detection. It is noted that the complexity of the “estimator” (i.e., prediction filter) and “correlator” (i.e., sequence search) can be varied independently. This concept is demonstrated for flat
