Adaptive Noise Cancelaltion - KULKARNI ANAND - Jun 11 5:52:00 2003

Hi All, We are trying to implement an adaptive noise canceller alogorithm in real time using 5402 DSK. To acheive this we need to give 2 inputs to the DSK i.e one is source signal and another one being the noise signal(which would act as a ref. to the adaptive filter.) But 5402 DSK has only one mic input, ofcourse another one is a DAA interface hooked to telephone line. Has anybody implemented single channel adaptive noise cancellation on 5402 or on any other DSK? if yes kindly let me know how could you work out the arrangement for the inputs? Thanks in advance.
