Theoretical analysis for the downlink spectra efficiency of DS/CDMA cellular systems in rayleigh fadin environment
This paper presents an original exact analysis on the downlink spectral efficiency of DS/CDMA cellular systems in Rayleigh fading. We derive a new expression for the probability distribution function of signal to interference plus noise ratio (SINR) which accordingly leads us to propose explicit clo...
