  Currently, the potential of microsimulation in space time trellis code has
not been thoroughly ascertained. Therefore, this letter explores the
possibility of using microsimulation in performing a pairwise comparison
between competing generator matrices in code design. The validation of code
construction is often done with simulation, which can be inherently time
consuming. Microsimulation considerably cuts down the computational cost of
simulation by employing smaller data and iteration. The effort is made 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.
