Software Defined Radio (SDR) & Cognitive Radio
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.
