The Worldwide Interoperability for Microwave Access is the IEEE 802.16 family of standard. The IEEE 802.16 standard defines Wireless MAN (metropolitan area network). The IEEE WiMAX/802.16 standard for broadband wireless metropolitan area networks (WMANs) can deliver high throughput over long distances, and support different qualities of services, offers a wireless backhaul network that enables high speed internet access to residential, small and medium business customers. This promising and cost-effective technology can also support internet access for Wi-Fi hot spots and cellular base stations through their respective access points . It has been designed to provide high data rate communication in metropolitan area wireless networks . The WiMax, for broadband wireless access is employed for high speed and low cost, which is easy to deploy, and provides a better alternative for extension of fiber-optic backbone. The base stations of WiMAX can provide greater wireless coverage of about 5 miles, with LOS (line of sight) transmission within the bandwidth of up to 70 Mbps. In this paper, we evaluate bit-error rate performance of WiMAX system using zigzag with RS coded modulation for different code rate and code length. The results show that the proposed zigzag-coded modulation combined with RS coding presents a stronger error correcting capability as compared to the Reed Solomon with Convolutional code or only zigzag code.
