— Performance of cooperative spectrum sensing with multiple antennas at each cognitive radio (CR) is discussed in this paper. The CRs utilize selection combining of the decision statistics obtained by an improved energy detector for making a binary decision of the presence or absence of a primary user (PU). The improved energy detector uses an arbitrary(More)
This paper introduces the concept of an integrated in-strumentation environment (IIE) for multiprocessors. The primary objective of such an environment is to assist the user in the process of experimentation. The emphasis in an IIE is on experiment management (including stimulus generation, monitoring, data collection and analysis), rather than on(More)
In this paper, we consider a cognitive radio network containing two cognitive radios (CRs) and one primary user. The CRs utilize finite number of received data samples for estimating the energy of the primary signals and forward these energy estimates to a fusion center (FC). The FC combines the energy estimates and utilizes a global threshold based on the(More)
