How to compute RMS in frequency domain
Hi, my question is very simple: How to compute RMS in frequency domain? I do NOT want to transform signal to the time domain by inverse DFT(FFT) and compute then the RMS. Is there a way, how to compute RMS directly in frequency domain? The signal is general (random), not only sine waves. Thanks in advance... 11 Feb 2010 11:38
Kalman Filter applied to Rangefinding Data
I must be missing something. I passed 128 records of 1300 samples each (1300x128) through a Kalman Filter (This is basically a laser return signal - often times quite small- buried in solar noise generated by an APD - Avalanche Photo Diode) and the output appears as noisy as any one of the record inputs. Simple Avera... 26 Jan 2010 02:12
How i can estimate Eb/No using a FFT

My doubt is how i can get first Es/No, and second Eb/No (I suposse Eb = Es/3  for 8FSK) I think that it could be, fo... 22 Jan 2010 10:36
Nonbinary or binary LDPC?
>It is known nonbinary LDPC may have some improvement in performance over binary LDPC. However, decoding complexity is also higher. So is it interesting to consider nonbinary LDPC codes in real application? Hi, I need nonbinary LDPC matlab codes. does any one help me to find. because it is really important ... 22 Jan 2010 09:28

implementing an fpga based on hilbert transform
I'm doing a project on developing and implemantation of a time domain set-up in a phased array mode using fpga based signal processing.It basically deals with hilbert transform module and phase correction of the signals.I have the vhdl code for all the modules required and i have to implement the hardware and ... 21 Jan 2010 08:53

midi lyrics
Hi all I need a cross-platform (linux, win) library for reading lyrics of a midi file. I have tried portmidi, rtmidi, libjdkmidi, sdl_mixer, allegro, FMOD with no success (T_T) I have to parse a midi file to obtain MetaEvents (which contain Lyrics). A source code example is really appreciated Thanks ... 3 Feb 2010 07:13
