Abstract EN
One of the most important problems of reliable communications in shallow water channels is intersymbol interference (ISI) which is due to scattering from surface and reflecting from bottom.
Using adaptive equalizers in receiver is one of the best suggested ways for overcoming this problem.
In this paper, we apply the family of selective regressor affine projection algorithms (SR-APA) and the family of selective partial update APA (SPU-APA) which have low computational complexity that is one of the important factors that influences adaptive equalizer performance.
We apply experimental data from Strait of Hormuz for examining the efficiency of the proposed methods over shallow water channel.
We observe that the values of the steady-state mean square error (MSE) of SR-APA and SPU-APA decrease by 5.8 (dB) and 5.5 (dB), respectively, in comparison with least mean square (LMS) algorithm.
Also the families of SPU-APA and SR-APA have better convergence speed than LMS type algorithm.
