Abstract

A Rake receiver is a radio receiver designed to counter the effects of multipath fading in wireless communications. It does this by using several “sub-receivers” each delayed slightly in order to tune in to the individual multipath components. Rake receiver preceding a maximal ratio combining becomes an optimum receiver in the sense of highest signal-to-noise ratio. A Rake receiver is part of the standard defined by 3GPP for WCDMA mobile systems. Multiple Input Multiple Output technology has attracted attention in wireless communications, because it offers significant increase in data transmission rates without additional bandwidth or transmit power. MIMO could increase spectral efficiency of a system. The main idea of this paper is to deploy a Rake receiver over MIMO antenna in Long Term Evolution - Advanced systems with the main aim is to further increase the spectral efficiency.
