Hi, I'm from Brazil and I'm using the MATLAB to generate a code for my DSP with the model that I have in Simulink. My DSP is a Blackfin 537 of Analog Devices. I need some information about the block Custom Board in Simulink the I use to generate a project in Visual DSP++. I create a subsystem with my controller and I use the Custom Board inside this subsystem. What I needed to know, is if t...

Dear All!! This is Vinod Patel. I need some help from You. Actually I am trying to simulate the PWM for selected harmonics elimination in transmission lines. For the same I want to store the 8bit X 1024 of binary bits in 1K X 8bit of memory block. And want to read the 8 bits at a time by giving the pulses generated from VCO (Voltage Controlled Oscillator) to the memory block in simulink. T...

Hi all, Anyone can help me on this?. I'm developing genetic-fuzzy control for a vehicle system. I need to optimize the fuzzy logic control using GA. At the moment I'm using Genetic Algorithm Toolbox (GAT)for MATLAB developed from Sheffield Uni UK, Simulink and MATLAB m-files. My question is, instead using that GA toolbox, can I just use th

Hello .. I have a major problem when trying to calculate the Exact SNR from the received symbols. Usually, in Simulink it is pretty simple to calculate the SNR per symbol by calculating the variance of the difference between transmitted and received symbols. This works perfect for the ZF receiver. However, for the ML receiver, this method is not possible any more bcuz the ML receiver map...

Hello, Here is what I have to do: 1. Get a live signal in Simulink using a sound card / dSPACE card 2. Using band pass filters, obtain band BF1,BF2,...,BFn 2. Calculate the sound level from each BF1,...,BFn. 3. Repeat this until an outside / hardware signal is get. Thank you for your time and help. Regards, D.P.

I am doing some analysis on an fft function inside simulink, that requires me to take the log10 of the incoming signal.  My input signal is a wav file and so the first frame is always zero, so when I want to take the ifft of the log10 function, I get an error and invalid data for the first frame.

hi jeff i am trying doing the same....can you plz guide.... I have implemented an OFDM communication system in Simulink. I am using Link to CCS and CCSv3.1 Platinum to build the model and transfer data to one TI C6713 board. The output of the board goes to the input of a second C6713 board. > > The problem is I do not know how to transfer the received data (from the second board) back to simul

Hello all, I am a beginner with simulink, and I would like to know how could I generate a block which gives as output the samples of a stored data. I have this data stored in a binary file (file_name.bin) and each byte of the file represents a sample. The thing is that I can not load the whole signal to the workspace, because it is 1 GB. Is there any way to make this block to read the ...

Hi, I am trying to run a Simulink electrical simulation that requires very high precision at certain times during the simulation. The problem is not to set the precision at high level, this can be done easily by changing the Max step size to a very low value. (I have found the value that is required for my simulation.) But by doing this, a memory problem appears, I need to simulate for a...

Hi, I'm trying to access Simulink from c#. 'sfroot' command returns the handle to the root object. But, when I'm executing the same command from c#. It's returning me the string "simulink.root". I explicitly tried type casting this with object and also tried creating an object thru reflection in .NET, but no success :( Here's the piece of code: MLApp.MLAppC

Hi, I'm triyng to simulate a discrete modified PI control system in Simulink as blocks of z-transforms but the plant that is going to be controlled is a continuous one. So I need to sample the output of the plant(the controlled variable) in order to use this sampled signal as an input to the discrete controller. I've heard this could be done by using the "clock" block of Simulink but...
