Cognitive radio is an empowering innovation that guarantees to achieve spectrum
utilization. To manage the muddled wireless condition, cooperative spectrum sensing (CSS) …

When radars operate in coastal or offshore environments, an undesired signal known as
clutter appears as background in the measurements. The CA-CFAR detector is the classic …

The main problem faced by sea radars is the elimination of an undesirable signal that
appears mixed with target information: sea clutter. The clutter results from the echo caused …

Accurate threshold setting for energy detector is important for example in dynamic spectrum
access. This requires accurate statistical distribution models of the observed energy. In this …

Spectrum Sensing (SS) comprises the most important component in Cognitive Radio (CR)
systems. Cooperative Spectrum Sensing (CSS) is proposed as an effective approach to …

In this paper, we propose a sensing scheme based on energy detection, matched filter and
cyclic prefix. Both Equal Gain Combining (EGC) and optimal combination of the …

In this paper, we evaluate the detection and false alarm probabilities for relay based
spectrum sensing techniques using the energy detector. The communication process …

The presence of the sea clutter interfering signal sets limitations on the quality of radar
detection in coastal and ocean environments. The CA-CFAR processor is the classic …

Los detectores de radar son los encargados de tomar la decisión sobre la presencia o no de
un blanco, realizando la discriminación del clutter que es una señal interferente. Con el …

A widespread methodology for performance analysis and evaluation in communication
systems engineering is network simulation. It is widely used for the development of new …
