OT: C macro to declare u32 from "ABCD" [11 articles]
Andre - 2012-03-14 20:51:00
Dear all,
I would like to handle a table of 4-byte long strings by just declaring
them as an array of unsigned 32 bit values.
Of course, this can be done manually, but it would be great if a mac...
unclipping [15 articles]
glen herrmannsfeldt - 2012-03-12 03:51:00
I have a digitized WAV file about 71 minutes long (actually, 10
files totaling 71 minutes) with three samples clipped, I believe
not all consecutive.
I can't actually hear them, as I usually can...LDPC - Parity Check Matrix , using: cyclpoly & cyclgen
wuid - 2012-03-11 11:28:00
Hi all,
i tried this for arbitrary matrix size:
%%%%matlab code
pol=cyclpoly(rows,cols); h=cyclgen(cols,pol); henc=sparse(h);
l=fec.ldpcenc(henc)
by doing that i am able to encode my msg wit...couple of questions on practical IIR filter implementation on fixed point systems [3 articles]
ok1iak - 2012-03-10 15:39:00
Hello.
I am a professional programmer, but I am doing DSP just as a hobby.
Three years ago I designed a morse / PSK31 decoder on a 16bit no-
multiplier controller. After rouhgly 3 years of absenc...using IIR or FIR to implement the lowpass filter for downsampling? [13 articles]
Nasser M. Abbasi - 2012-03-09 13:29:00
For downsampling (decimation) one normally uses low pass filter
before downsampling (anti-aliasing filter).
I have thought that FIR is the best choice here for the low pass
filter implementatio...basic bpsk bandwidth question [10 articles]
recoder - 2012-03-08 23:19:00
Dear All,
Assume that we have 1kbps data, if we BPSK modulate it on a 2 khz
carrier with 2 period per bit, we have a 1 khz wide signal centered
at 2 khz so the 3 dB bandwidth of the signal is 1 k...Anti-Cuttlefish Should Be Almost As Easy [2 articles]

Thomas - 2012-03-08 08:43:00
Hi all,
I am a newbie in DSP and need your help on understanding Hilbert
transform...
I have a real, double sided signal coming in. I want to use Hilbert
transform to get rid of the negative s...Texts on generic DSP architecture designs? [24 articles]
WaveRider - 2012-03-08 02:39:00
Hi everyone,
I'm an undergrad and I'd like to tackle the task of designing a DSP. I'm
wondering if anyone can help point me in the right direction in terms of
common considerations for DSP ISAs, co...Looking for a good (cook)book on audio signal processing [6 articles]
Mauritz Jameson - 2012-03-07 09:34:00
I am looking for some (cook)books on advanced audio signal processing,
audio effect algorithms, speech processing algorithms etc. Preferably
something that is up-to-date.
I am thinking about buyi...
