workspace coefficients in Simulink - Nalin Pithwa - Feb 28 20:43:00 2003
|
Hello, I am using MATLAB and Simulink based DSP/Communications Blockset in my application. I need a small help. In the design of my system, one of the blocks is a FIR filter. The filter coefficients are generated during run-time and they change adaptively. How can I use those filter coefficients, which are generated at run-time in the FIR filter in Simulink ? Is it possible to store these coefficients in workspace and access the coefficients from workspace for use in the FIR filter ? If so, how do I store them in the workspace? If this is not possible, what is the other alternative? Thanks in advance, Nalin |

Hi Nalin, You have not mentioned how you are generating the coefficients. If it is generated within simulink by some other blocks then you can choose in the digital filter block from DSP Blockset the option for coefficients coming from input port and feed the generated coefficients in that port. If you have an m-file then it is better to write an m-file S-function. You can also look at the existing adaptive filters in DSP Blockset.
