Abstract: In cognitive radios, a directional antenna can be used at the primary system receiver in order to improve reception performance. The problem is that the cognitive radio sensors may not detect weak signals from the primary system transmitter far away, whereas these signals can be received by a high-sensitivity primary system receiver. The present paper describes the experimental results obtained in field trials performed in order to demonstrate the impact of various parameters (e.g., directional gain, reflections, and diffractions) in spectrum sensing.
