Transmitter Configuration with 4 Uniformly Deployed Antennas for Spatial Modulation Analysis

The experimental setup utilizes a standardized transmitter configuration with 4 antennas. We will systematically vary the number of receiver antennas to analyze their impact on spatial modulation system performance. To ensure comprehensive analysis, the experiment will incorporate additional receiver antennas to cover broader operational scenarios. This methodology facilitates thorough understanding of how receiver antenna count influences system parameters like bit error rate and spectral efficiency. From an implementation perspective, the antenna selection algorithm can be programmed using matrix operations in MATLAB or Python, where the transmitted symbol vector x is constructed as x = H*s with H representing the channel matrix and s denoting the spatial modulation symbol. The performance comparison may involve Monte Carlo simulations evaluating error probability across different antenna configurations, providing foundational guidance for future research and practical applications in MIMO system design.
