Equal Power Allocation vs. Water-Filling Power Allocation Strategies

In this function, we compare the channel capacity and outage capacity of MIMO systems under both equal power allocation and water-filling power allocation strategies. The implementation involves calculating the singular value decomposition (SVD) of the channel matrix to determine the eigenmodes, followed by applying different power distribution algorithms across these modes. Additionally, we investigate how different channel state information (CSI) feedback strategies impact system performance. The comparison includes analyzing capacity curves using Monte Carlo simulations and evaluating outage probability through cumulative distribution functions. By comparing and analyzing these different strategies, we can better understand MIMO system performance characteristics under various conditions and provide guidance for optimizing system performance. The code implementation features configurable parameters for signal-to-noise ratio ranges, antenna configurations, and feedback delay models to facilitate comprehensive performance evaluation.
