چکیده

In this paper the wireless communication system with the receiver consisting of an automatic frequency control (AFC) loop is considered. Proposed system is subjected to k-μ multipath fading environment and single interference. Performance measures such as average switching rate (ASR) and mean time to loss of lock (MTTL) are investigated. Furthermore, closed form expressions for ASR and MTTL are obtained. Numerical results are graphically presented in order to show the influence of Rician factor and fading severity parameter on ASR and MTTL. Keywordsautomatic frequency control loop, average switching rate, co-channel interference, k-μ multipath fading, mean time to loss of lock.

Energy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels

In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...
