IEEE 802.16e mobile WiMAX is currently being developed as the next-generation communication standard competing with wireless local area network (WLAN), code division multiple access (CDMA), evolution data optimized (EVDO), enhanced data rates for GSM evolution (EDGE) and high speed downlink packet access (HSDPA), even though early applications for mobile WiMAX technology will be limited to high data rate communication purposes. This article discusses the key mobile WiMAX 802.16e radio frequency (RF) receiver requirements including NF, P1dB, IP2, IP3, and dc settling time to be able to identify RF system requirements. System simulations such as utilizing matlab software to extract EVM in different conditions including pilot tracking loop, will also be described to illustrate its effect with high-data rate mobile WiMAX system design.
IEEE 802.16e mobile WiMAX is currently being developed as a next generation communication standard competing with WLAN, CDMA, EVDO, EDGE and HSDPA even though early application for mobile WiMAX technology will be limited to high-data rate communication purposes. However, eventually these technologies will be competing with each other with various applications. IEEE 802.16e specifically targets mobility from previous IEEE 802.16 standards as it can be indicated from the standard . Orthogonal frequency division multiplexing (OFDM) is a multi-carrier modulation technique that transmits data over a number of orthogonal sub-carriers, which consist of data and pilot within various formats of frame structures.
