A New Band AMC Scheme for Military Use of Indoor Mobile WiMAX System
Indoor wireless communication systems have been developed to improve cell coverage and throughput with low cost in indoor environment. Among several indoor wireless communication systems such as Mobile WiMAX (Worldwide Interoperability for Microwave Access) system, WPAN (Wireless Personal Area Network) and WLAN (Wireless Local Area Network), the Mobile WiMAX is one of the promising next-generation wireless communication systems and considered for military use by the U.S. Army. In indoor environment, a band AMC mode which is one of sub-channel allocation modes in the Mobile WiMAX system is mainly used since it is appropriate to the fixed or low mobility environments. However, the conventional band AMC mode is optimized for the outdoor environment, so it will cause many problems in the indoor environment.
