Signal Processing Applications

Article

Radar, communications, and SIGINT [signals intelligence] systems have traditionally combined sensor processing, data conversion, and signal processing hardware within single enclosures or equipment racks. Analog signals for antennas, transducers and other sensors were connected through cables, often causing loss and interference along the way. However, enabled by new data converter and field-programmable gate array (FPGA) technology and evolving open embedded computing standards, system designers can now deploy small-form-factor (SFF) subsystems at each sensor site for distributed signal acquisition and preprocessing. Digitized signals are then delivered through optical cables, providing higher signal quality over longer connection distances while reducing size, weight, cost, and maintenance.[Continue reading →]

White Paper

SDR has revolutionized electronic systems for a variety of applications including communications, data acquisition, and signal processing. This handbook shows how DDCs and DUCs, the fundamental building blocks of SDR, can replace conventional analog receiver designs, offering significant benefits in performance, density and cost and much more...[Continue reading →]

Software Defined Radio (SDR) has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing. The inner workings of the SDR will be explored with an in-depth description of the internal structure and the devices used. Finally, some actual board- and system-level implementations and available off-the-shelf SDR products for embedded systems will be described.[Continue reading →]
