研究目的
Investigating the optimal LED placement strategy for an indoor mobile communication system to optimize communication system parameters including transmit power optimization.
研究成果
The HypEA-based LED deployment strategy achieves full receiver mobility with minimal LEDs and power consumption, outperforming uniform and centrally distributed LED models in terms of SNR consistency and RMS delay.
研究不足
The study is limited to indoor environments with specific dimensions and does not account for external light interference or dynamic environmental changes.
1：Experimental Design and Method Selection:
The study employs three LED deployment strategies for an indoor room scenario, comparing their performance in terms of communication coverage, SNR, and RMS delay.
2：Sample Selection and Data Sources:
The room dimensions are set to 5m × 5m × 3m, with the receiver placed at
3：85m above ground level. List of Experimental Equipment and Materials:
LEDs with a transmit power of
4：5 W, a PN/PIN detector receiver with an area of 1 cm2, and responsivity of 53 A/W are used. Experimental Procedures and Operational Workflow:
The receiver's movement is simulated along the x-axis for fixed y-axis values to observe SNR variations.
5：Data Analysis Methods:
The study analyzes average communication area ratio, LED requirement versus semi-angle, RMS delay, and SNR fluctuations.
