Abstract

Computer Networks--Local Area Networks Signal Processing--Correlation Detectors Coherent Recombination Matched Filtering Optical Correlation Optical Ladder Networks Spread Spectrum Communications Star LAN Laser Pulses
Coherent recombination by matched filtering of a series of pulses derived from a single laser pulse, using optical ladder networks is shown to result in a highly single-peaked correlation function. When this coherent correlation is generated using a low coherence source, the technique may be used in a local area network based on a star topology. This provides a more practical but equally powerful alternative to other current proposals.
