Abstract
A signal receiver for use in a system for communication and telecontrol over the electricity mains network has a correlation stage in which values of correlation coefficients for a received signal are predicted in a processor taking due account of known distortions of the network. Then these coefficients are multiplied, shifted and averaged with recent results to minimise the effects of noise, the consequent values being multiplied by the actual correlation values of the received signal in the bins for comparison.
