 Nick:
      You've definitely picked a tough subject to start out with. 
 Adaptive filtering techniques involve changing the filter coefficients 
 in a predictable way and also in many cases the range of coefficient 
 changes are also controlled so that the system doesn't become unstable. 
      It would be much better to start out with basic filtering 
 algorithms. A good reference is "Discrete-Time Signal Processing", Alan 
 V. Oppenheim and Ronald W. Schafer, Prentice Hall, 1989. I have it and 
 have been reading through it as a review. It uses current terminology 
 and is up to date on what techniques are useful.
      Thanks for your feedback and interest in the conference. I will 
 begin posting messages on how to actually generate coefficients for 
 filters before too long. FFT's are very important to FIR filter 
 coefficient generation.
