We develop and investigate a distributed algorithm for signal subspace tracking with a wireless sensor network without the need for a fusion center, in order to improve the robustness and scalability. We assume that all sensor nodes may broadcast messages to sensors in their neighborhood defined by a finite (small) communication radius. To this aim, we start from projection approximation subspace tracking (PAST) which is a well-investigated algorithm suitable for implementation in a fusion… CONTINUE READING
