  This letter explores the possibility of using microsimulation in space time
trellis code. Performing a pairwise comparison between generator matrices is
essential in the validation of optimality. This is often done with simulation,
which can be a time consuming process altogether. Microsimulation considerably
cuts down the computational cost of simulation by employing smaller data and
iteration. The effort is feasible with the assistance of a machine learning
model known as multilayer perceptron. When properly conducted, it can offer
93.86% accuracy and 98.25% reduction in temporal cost.
