Random Correlation Detector
Hi all,
The Project: Detect objects at some distance using Infarred
emiter/detector system using pseudo random signal.
The Problem: Does some method already exist to correlate an incomming
IR/PRN signal to detect it in the presence of other IR signals with
other PRN sequences?
