Dsp lib: function dsp_adaptive_lms() have undesired outpu
Posted: Wed Jul 03, 2019 4:02 am
I try to use adaptive filter to do some signal procession. When I input a 1K Hz sine data as input sample and reference sample for the dsp_adaptive_nlms(), return output is strange. I use printf to get the output data is all show 7FFFFFFF and 80000000. Whether do I misunderstand the function usage ? Please help.
adapt_array[128]= 7FFFFFFF 7FFFFFFF 80000000 7FFFFFFF 80000000 7FFFFFFF 80000000 8000000
