6 Spectrum sensing and cognitive radio
6.1 Introduction
Cognitive radio is a technology which is being developed to bring greater efficiency, speed and r...
6.2 Simulating spectrum sensing
The manual sets out how SEAMCAT can be used for spectrum sensing where the interfering devices (I...
6.3 Input system parameters
For the sensing feature to be activated, both the victim and interferer transmitters have to have...
6.4 Scenario parameters
In addidtion to the input system parameters, you also need to set charateristics of the spectrum ...
6.5 Examples
At the end of the simulation, SEAMCAT provides a set of output vectors as presented in Section 12...
6.5.1 All the channels are available
In such a scenario, the detection threshold is taken to a value of 0 dB (Figure 160) much high...
6.5.2 All the channels are blocked
In such a scenario, the detection threshold is taken to a lower value compared to the sRSS and no...
6.5.3 Some of the channels are blocked and some are available
This is a typical example. In such a scenario, the detection threshold is taken to a value of -80...
