Abstract

Abstract

In this paper,the updating equations of FBLMS and UFBLMS algorithms are transformed into the time domain,then two algorithms(FOBA and UFOBA) are presented by employing time-varying convergence factors which are optimized in a least-square(LS) sense respectively.Although FOBA and UFOBA algorithms require a relatively modest increase in computation for each block iteration compared to FBLMS and UFBLMS algorithms respectively,it is shown by simulations that these algorithms improve convergence speed and accucary of adaptation.
