A Survey on Energy–Efficient Spatial Filtering in Wireless Communication

A. Nandakumar

Abstract :

Spatial filtering, we review the literature on signal processing technique to control the directional for both transmission and receiver side. we are growing concern of energy efficient. Various strategies of improving the energy efficiency of adaptive Spatial filtering, efficient cooperative communication, network coding, etc was proposed. We proposed the cooperative Spatial filtering using mode switching algorithm. The main problem of Spatial filtering is unwanted signal appeared. The issue overcome using mode switching algorithm and also exists the RLS–QRD algorithm and array signal processing was exists. These analytical(algorithm) starts with the Single User Single Output(SISO) and Multiple Input Multiple Output(MIMO).
