In this paper, performance of energy detector is analysed over Rayleigh fading environment
using different diversity combining techniques. The channel is considered as Independent …

Cooperative relaying was introduced to make use of the broadcast nature of the wireless
channel, which provides spatial diversity to combat multi-path fading. Multiple antennas can …

To perform spectrum sensing in fading environment is one of the most challenging tasks for
a CR system. Diversity combining schemes are used to combat the effect of fading and …

In this paper, the performance of an energy detector in cognitive radio, using different
diversity combining techniques, is evaluated. Among many diversity combining techniques …

High data rate capacity and large coverage area are the main challenges for future wireless
communication systems. Mobile communicators are required to be power efficient and …

Cooperative relaying exploits the broadcast nature of wireless channel and extracts spatial
