Optimal FFT algorithm for hardware implementation ? The FFTW source code and design will be a good source but in general for new hardware design it may not provide too much insight because it was designed to be an optimal FFT for current processors (ie Intel, etc). There is an interesting forward in IEEE SP Magazine from the last couple months that touches on the ... 7 May 2008 14:04
What's the use of a 192 kHz sample rate? Manolis C. Tsakiris wrote: ... in DVDs the audio signals are modulated digital pulses (and not analog waveforms), such as PCM, and their spectrum is no longer that of an acoustical signal (20Hz-20kHz), justifying the need for a higher sampling rate. That sounds like doubletalk to me. Would you pl... 7 May 2008 13:14
FM Broadcast Stereo Pilot Detection Is there a digital technique for detection of the 19 kHz stereo pilot on commercial FM broadcasts? I'm looking for a way to extract the unmodulated pilot tone (only) from the analog RF carrier at low C/N ratios that would be below threshold with a conventional discriminator. Thanks. ... 7 May 2008 13:14
Newbie to DSP - Phase shift detection Hello everyone. I'm completely new to DSP, coming from a background of PIC18. I have two mics that I want to use for sound direction detection, and I guess using fourier transforms to get the freqs out from one channel then looking for a rough match in the second channel over time (and vice-versa) is the co... 7 May 2008 12:24

Rayleighchan function in matlab Dear all, I am trying to model a multipath in matlab but I do not have the communications toolbox and so neither the raileighchan function. I would appreciate your help on assessing if my approach to generate the FIR discrete channel is correct. I have two vectors containing the complex gain and the delay of ... 7 May 2008 12:24
