MATLAB Implementation of Power Control Algorithm for LTE Femtocell Networks

This MATLAB code demonstrates power control implementation in LTE femtocell networks. The simulation includes two femtocell base stations (FBS) and one femtocell user equipment (FUE). The code implements a power control algorithm to optimize network performance through several key steps: - Initialization of femtocell base stations with configuration parameters including position coordinates and initial transmit power settings - Distance calculation between base stations using Euclidean distance formulas - Path loss computation between base stations based on log-distance path loss models, incorporating factors like distance exponent and reference loss - Implementation of power control algorithm that dynamically adjusts transmission power based on received signal strength indicators (RSSI) and signal-to-interference-plus-noise ratio (SINR) requirements - User equipment initialization with position parameters and distance calculation to serving base stations - Performance evaluation through Monte Carlo simulations testing various channel conditions (including fading models) and different user population scenarios - The code includes visualization components for analyzing power allocation patterns and network performance metrics - Key functions include powerAdjustment(), calculatePathLoss(), and simulateNetwork() which handle the core algorithm implementation This implementation provides a practical framework for understanding and optimizing power control mechanisms in LTE femtocell deployments, with modular code structure allowing easy parameter modification and algorithm enhancement.
