An Efficient Communication System for Wireless Regional Area Network using Digital Modulation Techniques

Keshavamurthy, Dr. M. Nagaraja, Dr. M. Z. Kurian

In this paper, a Digital Communication System of Wireless Regional Area Network is designed using MATLAB. Here we use Convolutional encoding for the data bits generated by binary source. Randomization and Interleaving of the data bits is employed to remove various errors that occur in Digital Communication System. Different modulation techniques are employed to achieve maximum data rate and minimum Bandwidth. AWGN and RICIAN channel models are used which demonstrates the effects of multipath fading in air interface. Signal to Noise Ratio and Bit Error Rate are the parameters which are used to compare the performance of WRAN.
