Abstract
A process for non coherent DP-MOK reception with combination of multiple paths and corresponding receiver. The process includes demodulation of orthogonal signals (MOK) which is combined with differential phase demodulation (DP) and diversity processing related to multiple paths in the radiofrequency channel. Diversity processing is achieved making use of differential demodulation by calculating a weighting factor, this factor then being used in the MOK part (before selecting and switching) and in the DP part to correct the calculated energy.
