Simulation of Narrowband Flat Fading Correlated MIMO Channel Capacity

In the simulation of narrowband flat fading correlated MIMO channel capacity, we investigate the influence of several key parameters: antenna spacing, power angular spectrum, multi-cluster configurations, and total angular spread on both channel capacity and correlation coefficients. The implementation typically involves generating correlated channel matrices using Kronecker-based models or geometric channel modeling approaches, where eigenvalue decomposition techniques are applied to compute the Shannon capacity formula. Through detailed analysis of parameter variations, we gain deeper insights into channel capacity characteristics and the role of correlation coefficients. Furthermore, we explore capacity trends under different parameter configurations to comprehensively evaluate channel performance. These studies provide accurate references and guidance for designing and optimizing narrowband flat fading correlated MIMO channels, with practical code implementations often incorporating matrix exponential functions for correlation modeling and water-filling algorithms for capacity optimization under power constraints.
