Abstract

This paper presents a conjugate gradient minimum output energy (CG-MOE) algorithm for frequency domain MC-CDMA receivers. The CG-MOE algorithm employs the basis of the conjugate gradient (CG) and minimum output energy (MOE) algorithms. The CG-MOE algorithm does not require training signal yet robust to the near-far problems. The CG-MOE has a comparable complexity to that of the recursive least squares (RLS) algorithm. The CG-MOE algorithm obtains the advantages of fast convergence of CG and blind multiuser detection of MOE. The simulations and their results are investigated in frequency domain MC-CDMA receivers.
