Decoupling of the N-soliton solution for a new discrete MKdV equation

We prove that the N-soliton solution for a new discrete MKdV equation can be decoupled into N components. These components satisfy the interacting new discrete MKdV equation, and approach single soliton solutions as t→∞. We present concrete expressions of soliton components in the case of N = 2, and illustrate the results.
