Abstract
In densely built-up areas, the transmitted signal from the base station mostly arrives at the mobile station as a multitude of partial waves from different directions. This is known as multipath propagation. This effect gives rise to multipath fading. Due to this, received signal strength decreases and sometimes unable to recognise. So characterisation and modelling of wireless channel is highly important. The received signal strength 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 in multipath environment and is composed of fast fading caused by local multipath propagation and slow fading due to shadowing. In this paper, the real time data is analyzed by separating slow fading and fast fading components using moving average filter and then individual approximation of their cumulative distribution functions (CDF) are compared with the theoretical Rayleigh distribution and lognormal distribution.
