Received Signal Strength Interpolation Method for One-Dimensional Movable Antenna Positioning

초록

This study proposes a received signal strength (RSS) interpolation method to find the optimal position of the movable antenna (MA). The receiver with one-dimensional MA measures the RSS at the uniformly sampled antenna positions and interpolates them to reconstruct the RSS for the entire antenna region. The optimal MA position with the maximum interpolated RSS value is chosen. Using the minimum required number of sampling positions from the Nyquist sampling theorem, the proposed MA positioning with the RSS interpolation method outperforms other MA positioning and the fixed antenna position schemes. © 2025 IEEE.
