The following is excerpted from Chapter 18: Software Defined Radio from the Book, RF & Wireless Technologies by Bruce Fette. If you order a copy of this book before December 31, 2007 you can receive ...

If you haven’t heard about Software-Defined Radio (SDR) by now, you certainly will soon enough. The idea behind SDR has been around for over 30 years, but it’s only recently that it has started to ...

Making a software defined radio (SDR) receiver is a relatively straightforward process, given the right radio front end electronics and analogue-to-digital converters. Two separate data streams are ...

Overview of software-defined radio principles and an introduction to modern cognitive radio techniques. Fig 1. A conventional legacy radio receiver (a) uses the standard analog superheterodyne ...

Software defined radio or SDR is the most exciting frontier in the field of radio, transferring as it does all signal functions from the analogue to the digital domain. Radios using SDR techniques can ...

There is a new breed of RF receivers known as software-defined radios, and they are revolutionizing the way in which people listen to shortwave (SW) radio, or indeed any form of radio broadcast. SDRs ...

The scaling of CMOS technologies typically has a great impact on analog design. The most severe consequence is the reduction of the voltage supply. Imec and Renesas have managed to put a complete, ...
