Software Defined Radio (SDR) has taken the communications world by storm in the last
decade. SDR attempts to minimize the amount of fixed, non-reconfigurable content in a
radio and to maximize the amount of reconfigurable content. At first, doing so meant
using digital signal processing (DSP) technology to handle the detection, demodulation,
and processing of RF signals, but still relying on fixed front end circuits and antennas
for initial reception. Now, as integrated circuit (IC) technology gets ever faster and
more sophisticated, at sub-microwave frequencies the incoming signals are being sampled
and downconverted without the need for mixers, local oscillators, filter banks, and associated
circuitry. Even fixed antennas are sometimes being replaced with electronically steered
phased arrays - in some cases integrated right onto the IC.
Cognitive radio exploits the capability provided by SDR to add an intelligent, adaptive
nature to operations. It is capable of learning how to most effectively use its features
and reconfiguring modes of operation to be the most effective and efficient. These are
exciting times in the radio realm.
It is difficult to find vendors who make devices specifically marketed as SDR components,
but most of the top name and even a lot of specialty companies are slowly listing SDR
and cognitive radio as potential applications for their products.
