adpative filtering limitations
Hi all,
I'm simulating a transmission under simulink. Here are the characterisics. emitter QPSK modulation Factor 2 oversampling channel Fir filter [1 0.2 1 0.2 0.3 0.5] case 1 filter [1 0.2 0.1 0.2 0.3 0.5] case 2 receiver adaptive filtering (LMS algorithm) In the first case my filter does estimate properly the channel wherease in the second case i recuperate a good constellation. My question is , are traditional adaptive filtering technics still working when the transmission channel superimpose several path with the same power as the main path. (case 1) Thanks for your help!
