Addressing the Design & Verification Challenges of Cognitive Radio and SDR
This webcast will discuss how simulation and test can be combined to address Cognitive Radio and Software-Defined Radio physical-layer design and test challenges.
The ability to support multiple radio standards, or waveform applications, is one of the primary attractions of software-defined radios. This flexibility introduces greater challenges in both design and test, due to expanded regions of operation including greater frequency coverage, wider bandwidths, varying performance requirements, and signal modulations ranging from simple constant envelope FM to high peak-average OFDMA with MIMO with signal formal formats such as Mobile WiMAX™ and Long-Term Evolution (LTE). It can also effect even greater separation between the baseband processing design teams and the RF design teams.
In this webcast we will discuss how to mitigate many of the risks inherent in SDR development and how to take advantage of the SDR's inherent flexibility to improve the design and test process.
We will then introduce the concept of a Cognitive Radio Algorithm and Development Testbed. Cognitive Radios, often based on SDRs, typically incorporate some form of spectral sensing as an input to the cognition engine. Testing the spectrum sensing and cognition algorithm performance using realistic spectral environments can be challenging. This testbed combines live, remote field RF spectrum sensing, whitespace algorithm development, OFDMA link simulation, and test equipment.
