Every time I use the Rayleigh multipath-fading simulator in simulink (v4.0) it induces a BER of about 50% in my communications model, even with FEC. I have tried changing all of the parameters in the simulator, but nothing seems to help. Even if I reduce the numbers of paths to one, and in

Hi all, I am calling a simulink model from m-file(script file) and passing parameters to blocks correctly. But the problem is when use the same commands to call the model from a function (from GUI), the values are not getting updated. Can anybody tell me that why this is happening, and what is solution for this. Thanks and Regards, Ashwini

Hello, I need to program a DSP using Simulink. I need to create a custom bloc with S-functions that i will later on implement on the DSP with Real Time Workshop. I want to make a simple noninlined s-function. First problem: I have created a S-function block with Simulink -> User Defined Functions -> S-Function Builder. Only one change I made: in the "Outputs " tab I have written y0 = u0 + 1.

Hi guys, I'm working on a project with fixed-point toolbox on Matlab. I need to seriously sum tons of fixed point objects, and found there's no vectorized method around to do so. Just found that "Matrix Sum" in Simulink might do what I need, but I'm quite not sure how to call those blocks from .m code. I traced that, and found that sdspmsumprod.mexw32 seems to do the magic, but there's ...
