Design and implementation of ANC algorithm for engine noise reduction inside an automotive cabin using TMS320C5510

Mohammad Ehsan Haji Ramezan Ali, Mahmoud Ahmadian Attari

Abstract

In This paper a design for implementation of an ANC system with secondary path and feedback path modelling on DSK. Digital signal processing (DSP) starter kit TMS320c5510 is used to process two adaptive units in this ANC system, the adaptive main control filter with filtered-x least mean square (FxLMS) algorithm and the adaptive modelling filter with the LMS algorithm for updating the adaptive coefficients. Some practical problems usually occur during hardware and software implementations are also considered. At the end, the achieved results from the experiment are compared with simulation results.
