The performance of cooperative spectrum sensing (CSS) with double threshold and censoring of cognitive radios (CRs) has been evaluated using maximal ratio combining (MRC) in the presence of Rayleigh faded sensing (S) and reporting (R) channels. Each CR senses the primary user through sensing channel and evaluates the energy of the received signal at its sensing channel input and performs double threshold...
In this paper, the performance of cooperative spectrum sensing (CSS) with censoring of cognitive radios (CRs) has been evaluated using a simple majority logic fusion in presence of Rayleigh fading affecting both the sensing (S) and reporting (R) channels. Each CR senses the primary user (PU) using a double threshold based energy detection over the sensing channel. Censoring of CRs is done on the basis...
