Signal Transmission Analysis Using 900 MHz Carrier Frequency with Rayleigh Fading Channel Modeling

In this communication scenario, a signal is transmitted using a 900 MHz carrier frequency through a multipath channel characterized by Rayleigh fading. The channel parameters include a Doppler spread of 10 Hz and 10 distinct multipath components. The primary objective involves generating the Rayleigh faded signal and computing the outage probability, defined as the likelihood of the signal power dropping below a threshold of -10 dB. To implement this analysis in MATLAB, we will model the path loss as a function of the loss parameter across distances ranging from 2 km to 40 km. The implementation requires using Rayleigh channel objects from the Communications Toolbox, specifically configuring the doppler spectrum and multipath components. Key functions include rayleighchan for channel modeling and berfading for outage probability calculations. The power loss in decibels (dB) will be computed using logarithmic transformations of the signal power ratios. Through comprehensive analysis of Rayleigh fading characteristics and outage rates, we can characterize signal behavior patterns and quantify how transmission distance impacts power degradation. This analytical approach provides critical insights for optimizing wireless communication systems in similar propagation environments, particularly for designing robust transmission schemes against multipath fading effects. The MATLAB implementation will include visualization of fading patterns and cumulative distribution functions for outage probability analysis.
