Abstract :

One of the wireless networks that have been studied in recent years is the WiMAX network. Multi-antenna techniques are used in WiMAX systems to increase coverage and reliability of transmission and reception. The design of multiple antennas provides many benefits such as array gain, diversification gain, and elimination of co-channel interference. Multi-antenna technology support is a key feature of WiMAX compared to other wireless broadband technologies (such as HSDPA). To increase coverage and reliability, IEEE 802.16-2004 standard WiMAX systems support multiple antenna techniques such as space-time coding (STC), array antenna systems (AAS), and MIMO systems. In this paper, we focus on techniques that do not require channel information in the transmitter, such as STC and MIMO and compare the results.
