    Operational tests and demonstrations of systems based on software radios are currently being performed in the 800 MHz mobile cellular radio band. These field trials are for mobile unit geolocation systems and adaptive phased array “smart antenna” applications. The geolocation system trials are in response to the demand for high confidence geolocation of mobile units for enhanced emerge... View full abstract»

    Rapid advances in hardware development of analog-to-digital converters (ADCs) have paved the way for development of radio receivers using digitization at the IF, and in some cases, at the RF. The constraints placed on these receivers due to hardware limitations of these devices are discussed and some examples of high-speed, state-of-the-art ADCs are given View full abstract»

  • The DSP bottleneck

    Publication Year: 1995, Page(s):46 - 54
    Cited by:  Papers (45)  |  Patents (109)

    The stumbling blocks in development of a commercially usable software radio have been the availability of hardware, in particular the fast DSP required. As high performance ADCs have become available commercially, with the sample rates and spurious free dynamic ranges required, hybrid techniques using specialized digital hardware, operating under software control, have become more common View full abstract»

    The resurgence of interest in the combination of fiber and coaxial cable has led it to the acronym HFC, for hybrid fiber-coaxial, since it is no longer just the province of cable TV. Many telephone operating companies in North America, Europe, and Asia are moving rapidly to install this type of cable plant, both for its high capacity and for its relative simplicity and ease of maintenance. This is... View full abstract»
