Affine Projection Algorithm
>>Thanks for that. Is there an equivalent Wiener filter for the APA method or is it just that the APA method gives a more accurate Wiener solution in the stationary noise case? ie they both minimize mse?

EVA, EPA and ETU channel fading models
Hi, I am not sure if the is the right forum for this kind of question, but I wanted to know if the channel models specified in the 3GPP standard (3GPP TS 36.104, annex B), namely extended pedestrian A model (EPA), extended vehicular A model (EVA) and extended typical urban model (ETU) use Rician or Rayleigh fading. ... 11 Jan 2010 00:00

some help please on more efficient way to detect tones?
I could use some help, since I am very new to DSP. Here is my situation: I am recieving I/Q data at 250kHz rate, demodulating it with demodulation algorithm: IdQ+QdI/I^2+Q^2. Then storing 800 samples and using the Goertzel algorithm to detect 4 different tones. Currently the DSP cannot calculate all of this and ... 11 Jan 2010 16:28

conventional wisdom how to upsample very large arrays, accurately?
Hello all, I'd like to know what methods are available, if any, for upsampling a large array. I have an application where I need to sinc interpolate an array of 1E9 (billion) double precision data points output by an ADC by 4x. The array captures a clock waveform centered at zero volts and is oversampled (meets ... 13 Jan 2010 06:30

Interpolation response overshoot, why?
Hi, When simulate the FIR filter response, run interp(Matrix,n) in matlab, the maximum of Matrix is 1,but the response is larger than 1? I wonder know why this could be happen and how to degrade this effect? B. R. Thanks. ... 10 Jan 2010 16:19
