Spectrum Allocation and Power Control in OFDM Systems for Cognitive Radio Networks

On the Performance of an Improved Energy Detector with Threshold Modification for Cognitive Radio Networks

“…The missed detection probability is given as (18). where 𝑙 1 , 𝑙 2 , 𝑙 3 is expressed as 𝜌 2𝐿−1 1 , 𝑚𝛾, 𝜆 𝑘 respectively and 𝐾 𝑢 is defined as Kummer's solution provided in [27] in which 𝑧 1 , 𝑧 2 , 𝑧 3 are Γ(2𝐿 − 1), 𝜆, and 𝛾 respectively.…”

“…However, ideal CSI isn't practically accessible and hence, detecting execution with defective CSI ought to be assessed [11][12][13][14]. The few works on modified threshold have been presented in the literature with an uncorrelated and limited number of users as [15][16][17][18][19].…”
