Hello, I am interested in altering a model that I've put together and run earlier using simulink. It's simply a two-input plant, with scope output; earlier I'd had a sine wave input, but I would like to change to a matrix(from file) as source. So I've taken a matrix from the 'source' collection, and attached it to the main part. The para

Hello all, I am facing a problem with the Queue block provided in SIMULINK signal management library. From the Help guide it is said that it could accept scalar, vector, or matrix input. However when I tried to input a 1x9 (same when I tried 9x1) data, it prompts error message saying that it only accepts scalar input. I could not find any configuration which could help, can Queue block acc...

Hello I'm working on the implementation of ofdm running on dsps(TMS320c6xxx). I have made my own simulink and matlab mfiles. My question is: Does any one know how to test my work on dsp basd on relating the dsp with my computer by using realtime workshop on matlab 2008 and see how my simulink goes on dsp without writing c or dsp's programming code composer?and then how to optimize this? please ...

Hi everyone. I just want to plot the QPSK baseband spectrum from the output data of the QPSK simulink block. However the output of this block are the symbol coordenates in the signal space and when I use "spectrum scope" i don't get the theorical spectrum for the qpsk (the sinc function..). How can I do it? Can I use the qpsk block? thanks in advance!

Hi All, i hope i can declare what i need . in order to implement the system using fixed point presentation we should run the system on simulink "we couldn't find a away to present sys with fixed point within ordindry m file if there was a way we hope to know it" . so to convert our m-file functions into simulink blockes w

hi all, i'm haveing an issue regarding the setting to simulate a discrete/continuous mixed model (continuous time delta sigma modulator) in simulink, particularly when i introduce excess loop delay (in continuous time) in the feedback. when i use different types of solvers, different max step size and different loop delays, the results are significant different from each other. ...

Hi, I would like to know if there is any way of reconstructing the input signal of a rician or rayleigh channel block in simulink, from the values of the output signal and the data given by the complex path gains port. Thanks in advance!

Hi all I have asignal sample at 27Mhz (jittered clock). I want to process the signal with a jitter free clock. So what shold be the clock freq at which i shold resample the signal. How do i resample an already sampled signal. If i want to say hold the sampled signal and then again resample with saome different clock, how do i modell all this in simulink.Need suggestion ASAP. Thanks & Regard...

Hello, I wanted to understand how RTW(Matlab) generates code for video capture for image processing on the dsp. The 'From Video Device' block in Simulink is not supported by RTW. So I just wanted to know what it is that RTW does when generating C code for CCS? Does this block have to be removed and RTW generates something automatically or is there another Simulink block that we have to put in...

hi friends, i am making a model in simulink and using a c6713 dsk and i want to use its ac23 codec's mic in port in stereo mode. signals coming from the left and right channels need separate processing. the project is a quadrature demodulator were the left channel gives me inphase (I) signal and the right channel gives me quadrature (Q) signal. this Q signal is to be given to a hilber...

Hi all, I met a problem in Embedded Matlab function. It seems that this customrized block does not support frame based signal. And according to the manual online, it is said "Simulink frames are not supported. However, you can use the Rate Transition block to convert frames into vectors." I can not understand it. Does that mean I can not use the batch processing? So this Embedded Ma...

Hi, I'm doing a project of single phase multilevel h-bridge inverter using the simulink. If i'm using the igbt block, and switching using the pulse generator instead of PWM generator, how should i setting the triggering time to get the good sinusoidal output. And also, can I use the universal bridge instead of IGBT block and how to use it since I'm very new to the MATLAB Simulink.

Hi I'm tring to make an "if" statement over a [512*2] matrix generated from the "from wave device" block in simulink. but I don't know how to make the comparition between the matrix elements and an scallar, because it seems that the "if" block only accepts scalers not matrices or vectors. any answer will be appreciated.
