A Novel Study on an Optical Wireless Indoor System Based on Artificial Neural Network

Abstract: Communication is one of the important aspects of life. High-speed wireless optical communication links have become more popular for personal mobile applications. Compared to the radio frequency domain, optical wireless communication offers much higher speeds and bit rates per unit power consumption. This work investigates the use of artificial intelligence and wavelet analysis as the main elements of indoor optical wireless communication receiver. The work uses the MATLAB tool for providing effects of Inter-symbol Interference and light interference on this receiver. This work presented focus mainly on the use of software based technique like continuous wavelet domain as an alternative for handling difficulties associated with these systems. In this, different modulation techniques like OOK and PPM are presented. The performance of this system will be analyzed based on BER value.
