circular convolution
I'm perusing the web and I suspect worse case I'll grab a few texts to further assist me, nonetheless, given two sequences ( radar application ) - reference and receive of length 1024. It was explained to me that the for linear convolution, I'll pad the sequences with zeros, then compute the FFTs. For circular con... 27 Sep 2006 06:38

Understanding Digital Signal Processing by Richard Lyons
I've just ordered the DSP book by Richard Lyons and would like to know what math background is required to read it. My math background is limited to high school calculus and introductory numerical analysis. Is this enough to for Richard's book? If not, can anyone recommend what other math I need? Thanks for an... 2 Oct 2006 09:10

OFDMA
Hello, I am new in OFDMA for 802.16, I wonder how can we calculate bit per symbol in wimax ? does this depnds on modulation and coding ? supposing that we QPSK 3/4 ? how can I know the number of bit per symbol ? thanks, Aleen ... 18 Sep 2006 12:44

A question for the RSCB (Was: Re: Big K - Laying The Ghost)
Do the RSCB and its directors support the cowardly behaviour of those who masquerade as others and cause offence? Do the RSCB directors speak out against such behaviour, or do they condone it and encourage it by letting such behaviour pass unremarked? Do the RSCB not realise, perhaps, that such behaviour comes ... 16 Sep 2006 12:59

using the edma channel of c6713 dsp
Hi all. I am trying to use the edma channel of my c6713 dsk, in order to take 8-bit data, from a daughter card (address 0xA0000000) and store them in the sdarm (address 0x80000000). Can anybody tells me what i have to do? Which functions i have to use? I have written a code based on the data sheets but unfortu... 18 Sep 2006 03:36

simple scrambler / descrambler
Hi, I'm looking for a simple scrambling and descrambling algorithm. My input is 6 4-bit values (nibbles) and I want it to be scrambled into 6 random looking nibbles. The descrambler of course must reverse the operation. The input signals represent low values with lots of leading zero's. So they look alike a l... 19 Sep 2006 08:35

Rayleigh Channel for HIPERLAN2 simulations
Dear All, I used to simulate the OFDM chain of HIPERLAN/2 in a multi-path channel. The channel model I used is a tap-delay fixed model of 8 paths. Each path, has a fixed attenuation and fixed delay value... % Attenuation values of the delayed taps (in dB). dB = [0 -0.6 -1.2 -1.8 -2.6 -3.6 -4.6 -5.6]; %Delays i... 16 Sep 2006 10:21

Booting the 56371 via serial EEPROM
Hello, I'm using the 56371 DSP and I have to boot it with serial EEPROM in I2C-Mode. The Procedure is described in the manual, but I do not know how to make a boot image from the *.cld file. I managed to make a .s file using srec.exe and then I converted that to intel hex format. Now, I don't know how to put the... 21 Sep 2006 12:44

DTMF decoder
Hi everyone, I am designing a dtmf decoder using the Goertzel algoritm, the problem is that I have +/-5% error on my sampling rate timing. Does anyone know if this is going to be a problem when calculating the results? Thanks in advance ivan ... 8 Sep 2006 11:00

Strobing inputs on DSKC6713
Hello - The ADC on the codec on the C6713 DSK multiplexes "mic" and "line" inputs. That is, you generally set the codec to grab samples from the mic input or the line input, which gives you two analog inputs - the left and right channels. Is there a fast way to "strobe" the line and mic inputs - using the ... 8 Sep 2006 11:00
