MATLAB OFDM Simulation
Does anyone know if there is a OFDM simulation in matlab is possible? If anyone has it, can you please share it with me. I have a final sem project that's due next week and am going crazy over this coding. SOS! Thanks. ... 1 May 2006 10:16

simulink
I have a simulation model for controling induction motor. I can get different simulation result in every executation time when I use simulink. It is very strange. I only have some C file s-functions in this simulation model. Do you think there are some problems with memory release ? By the way, I only write 'free'... 26 Apr 2006 15:09

ping: Jim Thompson
Jim, I was perusing your website and happened upon your patent regarding demodulating of FSK. Is this the currently easiest/best way to decode FSK? Or would I be better off doing with SW and microcontroller? I was thinking that a comparator with hysteresis to minimize noise could be used to 'square up' the inp... 26 Apr 2006 16:12

speech detection
Hi everyone, i have implemented my speech detection algorithm based on energy detection,zero crossing and a few other parameters. Now i would like to proceed further by using neural network and fuzzy logic.Anyone has any ideas how should i proceed? For example, in image recognition, i can use multilayer feed forward ne... 24 Apr 2006 07:40

IQ modulator &upconvertor(AD9857)
I am working on AD9857 which copmrises an IQ modulator and in fact is a quadrature up convertor Using 14 bits I Q input data , I want to try out various modulation schemes like AM, FSK,FM,BPSK,GMSK, QPSK and QAM. I`ve tried IQ modulation in different (analogue) shchemes with MATLAB using IQ in form of analog signals ... 23 Apr 2006 07:47

Default Configuration for TI DSK6713
Hi all! I'm working since not very much on a TI DSK6713. Despite having had some success with some examples and modifying them, I've not been able to create a project from scratch, using the Code Composer Studio that comes with it. This is not so bad, but still I'd like to create something simple and have some ... 20 Apr 2006 16:13

cma equalizer
hello,erevyone.Recently I have been designing a blind channel equalizer based on the Constant Modulus Alogrithm.But I have a question that I can't think over.The question is as follows: The alogrithm I use is below: y(k)= ¡Æf(k)x(N-k); % f(k+1)=f(k)-mu*e(k)*x(k); % e(k)=4*conj(y... 24 Apr 2006 14:59

Experimental analysis problem
Hi, I conducted a series of experiments into the effect of inter-aural signal differences on the perception of sound direction. I change two variables (the inter-aural time difference ITD, and inter-aural level difference ILD) and measure the human directional response. I change ITD by inserted blank sampl... 21 Apr 2006 06:15

Amplitude Response ?
Hi guys, I'm new to this stuff. I want to calculate the amplitude response so I can graph it, I'm using this example: y(n)=x(n)+x(n-1) Amplitude Response: G(w)=2.0*cos(Pi*f*T); According to the tutorial I'm using I think: f=frequency; w=2.0*Pi*f; T=1.0/sample_rate; ....but I'm not really sure beca... 20 Apr 2006 13:04
