Level Crossing Rate of Macrodiversity with Three Microdiversities in the Presence of Long Term Fading and Mixed Short Term Fading
Authors: , , , , ,
Abstract: In this paper, macrodiversity (MAD) reception with MAD selection combining (SC) receiver and three microdiversity (MID) maximal ratio combining (MRC) receivers is analyzed. Received signal in the first MID MRC receiver experiences Gamma long term fading and Nakagami-m short term fading, received signal in the second MID MRC receiver experiences Gamma long term fading and Rician short term fading and received signal in the third MID MRC receiver experiences Gamma long term fading and κ-μ short term fading. Level crossing rates of signals at outputs of MID receivers are calculated and by using these expressions, the level crossing rate (LCR) of MAD SC receiver output signal is evaluated. The influence of Rician factor of κ-μ short term fading, Rician factor of Rician short term fading, severity parameter of Nakagami-m short term fading, severity parameter of Gamma long term fading and correlation coefficient of Gamma long term fading on level crossing rate is studied and discussed.
