A Complex Probability Density Function: An Application to Multipath Fading Channels in Wireless Communication Systems
نویسنده
چکیده
An argument of common probability density function (pdf) is generally a real number, which describes the density, or mass in case of discrete random variable, of a random variable. However, in some applications, the pdf can be a complex function, so called complex probability density function. This kind of pdf is then, as general complex function, characterized by the amplitude and phase and is usually extensively used in quantum physics. In this paper the properties of complex pdf are investigated. The application to the multipath fading channels in wireless communication systems is also studied. Some models of multipath fading channels are given for supporting the validity of complex pdf in wireless communication systems.

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...

متن کاملMultiuser Detection in Shadowed Fading Channels with Impulsive Noise
In direct sequence-code division multiple accesses systems (DS-CDMA), the signals are transmitted over multipath channels that introduce fading. Multipath fading along with multiple access interference and intersymbol interference degrades the system performance. Further, simultaneous presence of multipath fading and shadowing leads to worsening of wireless channels. Moreover, experimental resu...
