Mobile WiMAX Key RF Receiver Requirements

چکیده
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.

Introduction The allure of the WiMax wireless high speed data service is well documented. Significant effort has been invested in developing a spectrally efficient modulation that is rather multipath impervious. Still, the laws of physics dictate that we need to get power from point A to point B that is above the receiver threshold. This requires rigorous RF planning and hardware design. Unlike...

متن کاملA direct-conversion receiver integrated circuit for WCDMA mobile systems
A prototype of a 3-V SiGe direct-conversion receiver integrated circuit for use in third-generation (3G) WCDMA mobile cellular systems has been completed. The goal of its design was to minimize current draw while meeting WCDMA receiver rf specifications with margin. The design includes a bypassable low-noise amplifier, quadrature downconverter, and first-stage variable-gain baseband amplifiers ...

A digital RF receiver front-end employing a DT filter is proposed for application to m-WiMAX & The SAW-less receiver architecture, where the large out-of-band interferer can be rejected selectively by using a scalable frequency response property of FIR filter. In addition to the flexibility of the DT filter, the new non-decimation finite impulse response (NDF) filter can be cascaded to a conven...
