Abstract

The IEEE 802.16 standard is often referred to as WiMAX today. It represents a distillation of the most advanced technology and an industry consensus permitting equipment interoperability. It holds the promise of delivering high speed internet access to business and residential customers and to remote locations where traditional broadband services are unavailable. In the present work, the PHY specified for the Wireless MAN-OFDM case is studied and implemented. Various modulation techniques involved are explored and each of the performances enhancing techniques is evaluated with regard to its functionality in the system. The simulation results show that the Space-Frequency Coded system coupled with Reed-Solomon codes and Convolutional codes efficiently exploits diversity techniques.
