Indoor Optical Wireless Transmission under Artificial Neural Networks

Abstract

Optical Wireless Communication now becomes important part in technology era. It is mostly used in newly developed mobile technologies. This work describes the concept of PPM based modulation under SWT and ANN. The use of SWT-ANN provides improvement in BER and efficiency of system. Focus on the modulation aspects of the optical wireless communication, this work is used for enhance noise immunity of channel by utilizing optimized modulation to the channel by use of ANN in receiver side. This ANN helps to reduce BER value of system and enhance the system performance. In this, modulation technique OOK & PPM is used. It uses ANN method to reduce BER value in receiver side. It compares the performance of OOK based format with PPM in terms of BER and efficiency value. All results are calculated using MATLAB tool and PPM is better in terms of BER and efficiency value.
