I wana implement (delayless)adaptive subband noise cancellation using polyphase filterbanks.
any help (thesis-paper-matlab source code-project report,..) would be appreciated.
I have problem in starting polyphast filterbank implementation in matlab :cry:
Need urgent help !!!!

I need to make a function for filtering dtmf-signals through a filterbank and detecting the frequencies and then figuring out which keys they correspond to.
detect=0; %sets detect to 0 before checking

1) Why mel-filterbank is important in speech analysis?
2) What is the main function of mel-filterbank and what happen to the input speech signal if we just ignore from doing this part?

This MATLAB program is for making a suitable wavelet kernel
It derives the Low pass filter by sampling from analog raised cosine function in frequency domain and taking ifft from this function to yield the impulse response. (other filters are derived using orthogonal relations).
first i wnat know if the filter design method has any problems?

if u r interested only in extracting a particular band of frequencies have a look at lyons cochlear model.
its a IIR filter bank with just 2 nd order filters.
u can google for Malcolm sanley or lyons cochlear model.
Matlab also has a filterbank implementation function. but only FIR.

a filterbank consists of both analysis and synthesis part....
look for the type of filter bank needed
then u must have an downsampler in the analysis part and some filters as per ur needs
and an exactly opposite filter to that used in analysis part must be used in the synthesis part along with a upsampler

Do a few searches for "template matching" in speech recognition applications.
Since you don't need continuous recognition or transcription you might not need something as complicated as Hidden Markov Models or Artificial Neural Nets. Maybe you want isolated word recognition?
filterbank analysis comes to mind as does Dynamic Programming as in

Thanks for the reply.
I am working on a digital filterbank design. I don't have the Schematics with me now. Attaching the input files given to Nanosim.
input.ckt - HSPICE netlist for the design
vdd3.sp - SPICE file to set supply voltage
gatelevel3V03.vec - vector file input

Hi, i am currently doing a project on speech recognition using a neural network. i have recorded all my sound sample and extracted it as a wav file. i have been able to read the wav file and display it on a time-domain graph and also a spectrogram.

You need to express your function as a linear combination of the new basis vectors. Do you have the basis vectors for v2 ?
I am interested in this subject please explain what is OFB and V2. May be I can offer some help.
OFB is basically orthogonal filterbank and V2 is the subspace which is represented at V2=V1+W1
