Abstract
The present invention relates to correlation apparatus in which samples of a received signal are demultiplexed and coupled to a plurality of correlators in cyclic fashion so that successive samples are coupled to a different correlator in the plurality. Each correlator provides an output which is coupled to multiplexing apparatus. This apparatus is especially useful for determining signal dispersion characteristics and avoids the 'null taps' associated with conventional correlation apparatus.
