Formatted abstract

Communication engineers have always been striving to design communication systems that could handle more channels, less noise, etc. At present, one of the frequency windows that can be utilised is fast becoming the choice of systems designers. We are now looking at deeper into the millimetre-wavelength regions of the spectrum, 97 GHz is chosen as the next microwave frequency to utilise for communications.

At this frequency, prevailing meteorological conditions such as rain and humidity can affect the reliability of the system. This would not normally affect systems of lower frequencies. Systems designers would require some means to estimate the specific attenuation due to atmospheric gases and precipitation.

This thesis presents programs written in Mathworks’ Matlab to specifically cater for the estimation of the attenuation caused by the atmospheric gases and precipitation. It will calculate the specific attenuation based on data given by the designer i.e. rain rate, distance of link, air temperature, relative humidity and air pressure.
