Location dependent variation of service quality

The effect of varying distances between the mobile station and base station on the Nakagami-m parameter is studied. A path loss model is developed that determines the received direct and scattered powers at the mobile station. The effect on the Nakagami-m parameter for different distributions of the reflection co-efficient P is also presented. It is found that the exponential distribution gives larger values of m as compared to uniform and half Gaussian distribution. It is observed that the transmitter and receiver antenna heights also effects the Nakagami-m parameter and an increase in their effective value enhances the performance of the system. A change in the operating frequency also effects the performance of a digital communication link. A new parameter Am is also introduced in order to study the impact on performance of the system with increase in distance.
