Our continued desire for increased wireless bandwidth for small and light portable devices have forced the development of novel transceiver architectures that accommodate wideband contiguous and noncontiguous data streams. This talk focuses on the use of discrete time analog signal processing for the development of low power, wideband transceivers for blind modulation classifying of signals. Blind signal classification is critical for spectrum surveillance and future heterogeneous wireless networks. This project is a joint collaboration with experts in signal processing and algorithms, low power VLSI design and analog/RF design. In this talk we will first focus on the analog architectures/tradeoffs and then briefly describe algorithmic and digital VLSI implementation details.
