The IEEE 802.16e standard, often referred to as Mobile WiMAXTM, specifies air interfaces for broadband wireless access (BWA) systems. The standard is expected to energize the BWA industry and open many opportunities to deploy systems in applications that were previously cost-prohibitive. Mobile WiMAXTM utilizes roaming and handoff to enable laptop and mobile phones operation.

E8869 Mobile WiMAXTM Wireless Library

Agilent's 802.16e mobile WiMAXTM wireless library provides signal processing models and preconfigured simulation setups for Agilent's Advanced Design System EDA software. Agilent's mobile WiMAXTM library provides signal sources and receivers to facilitate simulation of fully coded systems. The models and simulation test benches can be used as an analysis framework for simulation and verification of baseband algorithms, digital baseband/IF systems, and verification RF circuitry used in mobile BWA designs.

Agilent's 802.16e mobile WiMAXTM wireless library also can be imported into Agilent's RF Design Environment (RFDE), allowing RFIC designers to access Mobile WiMAXTM test benches within the Cadence Virtuo Custom IC platform through links developed as one result of the ongoing alliance between Agilent and Cadence.

This mobile WiMAXTM wireless library enables you to easily create waveforms that comply with Wireless MAN-OFDMA PHY in the IEEE 802.16e-2005 standard. Both the mobile WiMAXTM SISO (Single Input Single Output) and MIMO (Multiple Input Multiple Output) systems are supported. Moreover, this library provides transmitter measurements (such as EVM, CCDF and etc) and receiver measurements (such as receiver sensitivity, BER and etc).
