A Study on the Performance of IEEE 802.16-2004 Includes STBC

The era of entirely wireless, mobile communication is rapidly approaching. Increasingly, consumers are demanding versatile and convenient modes of communication that are available whenever they want, wherever they are; all of this without losing performance and efficiency. On the other hand, the demand for high-speed broadband and technology with less energy costs are growing side-by-side. The challenge is to give consumers high-speed, high-performance, mobile, and Earth-friendly alternatives to what is currently available. The answer to these demands might just be WiMAX. Worldwide Interoperability for Microwave Access (WiMAX) is a Broadband Wireless Access (BWA) technology that offers service to individuals and groups in subchannels. In this paper we aim to analyze the performance of IEEE 802.16-2004 including the Space-Time Block Coding (STBC) model and the Multiple-Input Single-Output (MISO). We found the rate of data transmission is being increased in certain models. For instance, 64QAM 3/4 performs efficiently with specific ranges of bandwidth. WiMAX could potentially be the answer to new consumer demands that the IT world has been in search of. Keywords—WiMAX; PHY; MISO; STBC; broadband; bandwidth; QoS; NLOS; PSD, MAC.
