Abstract
In this paper, we focus on the analysis and optimization of the interleave-division multiple-access (IDMA) system. The spectral efficiencies of the coded IDMA system are analyzed. Optimal power allocation among users in IDMA, to maximize the spectral efficiency with a finite-alphabet constellation, is also considered. Differential evolution is adopted to solve the power profile optimization problem.
