The dynamics of two counter-propagating waves in the Peyrad-Bishop-Dauxois model is investigated. We show using the reductive perturbation method that the dynamics of the system can be described by a set of coupled nonlinear Schrödinger equations. The relevant MI scenarios are explored and we note that the system is stable under the modulation for certain parameter values of the Peyrad-Bishop-Dauxois model. We also point out the impact of the group velocity on the stability of the system.
