VAlidation of Rayleigh pdf/CDF using real time mobile phone received data

The term wireless communication refers to transfer of information via electromagnetic or acoustic waves over atmospheric space rather than along a cable. Mobile signals propagate from base station to mobile station through space. During propagation they interact with objects. Due to obstacles and reflectors, the transmitted signal arrives at the receiver from various directions over number of paths. Received signal strength decreases and sometimes unable to recognise. The received signal in terms of power is measured using RF recorder for analysis at the mobile station at certain time intervals and the signal (in dBm) assumed to be received under homogeneous multipath conditions. In this paper the real time data is analyzed by computing its histogram (approximation of its pdf) and its CDF, and then verified whether the measured data fits a Rayleigh distribution using chi-square test.
