Abstract :
Interleave Division Multiple Access (IDMA) is a multiple access scheme where users are separated by the only means of interleavers. However, IDMA revealed to depend on power optimization because equal power repartition significantly deteriorates the performance when the system is heavy-loaded. Therefore, we propose the application of the genetic annealing Differential Evolution algorithm to SNR evolution for solving this optimum power allocation problem.
