Performance Evaluation of Mobile Networks by using Monte-Carlo Simulation
• Study the technical paper: “Area Spectral Efficiency of Cellular Mobile Radio Systems, IEEE Trans. Veh. Technol., July 1999.
• Develop Monte-Carlo simulation models to evaluate the performance of cellular mobile networks and study the effects of cochannel interference and re-use distances on the overall spectral efficiency.
– Factors you will consider and include in your study
∗ reuse distance,
∗ cell size,
∗ signal-to-noise ratio, ∗ path-loss exponent ∗ Rayleigh fading
∗ shadowing
– Evaluate the performance of the mobile network in terms of:
1. spectral efficiency,
2. area spectral efficiency and 3. outage probability.
• Submitacompletetechnicalreportwhichincludestheperformancecurves (with your comments on the results) as well as your Monte-Carlo simula- tion Matlab programs (with all necessary explanations).
• Due Date: Friday 11th October 2019.
• Marks Distribution:
– To get more than 50%, you need to provide simulation results for the area spectral efficiency in uplink transmission without fading or shadowing, taking into account interference from the 6 cochannel cells in the first tears first tear of cochannel cells
– To get > 60% you need to take into account the effects of both Rayleigh fading and log-normal shadowing.
– To get > 70% you will study and provide simulation results for the outage probability
Pr (outage) = Pr (SINR < γ) 1
where γ is a predefined threshold. You will plot Pr (outage) against γ for γ between 0−40 dB.
– To get > 80% you need also to provide simulation results for partially- loaded systems.
– To get 90%, you need to compare your simulation results for the spectral efficiency with theoretical results in “K A Hamdi, A Useful Lemma for Capacity Analysis of Fading Interference Channels, IEEE Trans. Commun, Feb. 2010, pp. 411-416”.
