  abstract={In this paper, we will compare different combinations ofa multi-channel non-adaptive noise reduction unit (NRU)and an acoustic echo cancellation unit (AEC) for a standardsingle-channel voice transmission. The results show thatthe NRU and the AEC-unit can be interchanged without increasingthe computational complexity of the combined system.The length of an AEC’s adaptive filter can be greatlyreduced, if a multi-channel AEC-unit in front of a multichannelNRU is used. Furthermore, the control information,like the step-size of the NLMS-algorithm, has to becomputed only once.},
