Introduction:With LabVIEW, engineers and scientists can acquire and output real-world signals, analyze data for meaningful information, develop embedded or autonomous systems, and share results with displays, reports, and the Web. Watch this webcast to learn the fundamentals of graphical programming and discover how LabVIEW can benefit your applications by providing data acquisition and signal generation, signal processing and analysis, connectivity with third-party hardware and software, and desktop, embedded and industrial deployment.

Introduction:Advanced OFDM (Orthogonal Frequency Division Multiplex) technologies impose additional challenges and requirements for testing new wireless communication devices and systems. This paper compares and contrasts traditional single-carrier modulation schemes with multi-carrier OFDM schemes to understand the test equipment and measurement considerations when using modern vector signal generators and analyzers. It covers in detail spectrum, power, and modulation quality measurements and techniques for R&D and high-speed production test applications. The paper covers testing of both SISO (single-input, single-output) and MIMO (multiple-input, multiple-output) communications systems used in 802.11n WLAN, 802.16e mobile-WiMAX Wave 2, which are also applicable to future LTE and UMB cellular standards.
