Abstract

The visible light communication (VLC) systems using light emitting diodes (LEDs) has been a promising transmission technology to complement wireless communications. In this work, a spectrum sensor array is proposed to be implemented on the receiver side. Following the concept of multi-antenna communication systems, signal fusion algorithm is presented. By proper design of the weighting for each individual spectrum sensor, the effective output signal to interference ratio (SIR) can be maximized and hence make interference rejection possible.
