A stereophonic low complexity subband adaptive algorithm

This paper presents a low complexity stereophonic subband adaptive algorithm that performs as well as the Fast Affine Projection (FAP) with a negligible additional complexity for the same order N. The new fast algorithm does not require matrix inversion thus alleviating the drawbacks of the FAP algorithm. Moreover, we will show that the algorithm reduces coefficient bias that appears in monophonic and stereophonic teleconferencing when the receiving room impulse responses are undermodelled.
