CR and SDR definitions by ITU<br />
• ITU = International Telecommunication Union<br />
• <strong>Cognitive</strong> <strong>Radio</strong> (CR):<br />
– Obtains knowledge from environment/user<br />
– Adjusts <strong>Radio</strong> parameters<br />
– Learns from results<br />
• Often a CR uses a Software Defined <strong>Radio</strong><br />
• Software Defined <strong>Radio</strong> (SDR):<br />
– Adjusts <strong>Radio</strong> parameter and protocols by software<br />
– At least frequency, modulation type, power<br />
– More flexible than predefined set by standard<br />
