Abstract
Wireless technology can be split into two major portions, mobile and fixed wireless infrastructure (Wireless Local Loop). Today, the demand for mobile systems is increasing with the passage of time from voice to higher data rate services. It is difficult to make mobile systems trustworthy for the services that practice a very high digital bandwidth such as triple play (Telephone, Cable TV and Internet), MIMO systems are used in 4G technology for high data rate services. A network is designed with the cooperation surrounded by the involved nodes to accomplish substantial improvement in the capacity of the entire system keeping improved Quality of Service (QoS). Cooperative networks can be used to minimize signal degradation and power reduction in most of the networks. Here, WiMAX LDPC technique is used in cooperative networks. Numerous models of fading channels have been utilized to examine the health of the communication system. The channel capacity approaching the coding method LDPC with the help of BICM is used to measure the performance with the main focus to analyze the performance measurements of WiMAX (IEEE 802.16).
