Abstract :
The paper investigates accuracy and compression achieved by applying FFA to two different forms of expressions for mutual coupling. In addition, the comparison is performed by compression obtained by ACA algorithm. In all these cases the influence of the group size and expansion order of higher order bases is elaborated.
