A computer model for simulating hybrid optical/digital cross correlators for pattern recognition is developed to investigate accuracy and limitations of a hybrid cross correlator compared to an ideal digital cross-correlator. The hybrid system is based on matrix-addressed LCD displays and CCD camera chips as interface devices. Both joint-transform and frequency-plane correlators can be simulated, and different physical distortion effects from ...

Timing synchronization for IEEE 802.11a WLANs 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 significant requirement can be eliminated by using multiplierless correlators. In this paper, multiplierless correlators are designed based on constraining the real and imaginary ...
Gallagher, D.R.; Kozlovski, N.Y.; Malocha, D.C. Ultrasonics Symposium, 2006. IEEE, 2006
This paper examines ultra-wideband (UWB) communication systems utilizing orthogonal frequency coded surface acoustic wave (SAW) correlators. Orthogonal frequency coding (OFC) and pseudo-noise (PN) coding provides a means for UWB spreading of data. The use of OFC spectrally spreads a PN sequence beyond that of CDMA because of the increased bandwidth; allowing for improved correlation gain. The transceiver approach is still ...

An all-lag reference code correlator generates an all-lag even-or odd-correlation vector at a rate equal to the rate of incoming data samples. Direct implementation of an all-lag reference-code correlator requires N parallel correlators, and the resultant degree of complexity is of the order N<sup>2</sup>, where N is the length of the reference code. This paper derives two recursive forms for ...
Gallagher, D.R.; Malocha, D.C. International Frequency Control Symposium and Exposition, 2006 IEEE, 2006
This paper presents the development of surface acoustic wave (SAW) correlators using orthogonal frequency coding (OFC) for use in ultra-wideband (UWB) spread spectrum communication systems. The use of ultra-short pulses, producing very wide bandwidths and low spectral power density, are the widely accepted approach for UWB communication systems. This approach is simple and can be implemented with current DSP technologies. ...
