HDL Coder Error while converting AWGN function code to Fixed-Point code. Any suggestion to solve it?
显示 更早的评论
I am using HDL Coder to convert AWGN function to Fixed-Point code as part of VHDL code conversion. but it produces an rrror while converting AWGN function code to Fixed-Point code. Any suggestion to solve it?
Can anyone help me how can I fix and solve the error? It very important.
Thank you for your help. Best Regards, Ghazanfar Latif

HDL Coder does not support any of the random number generators.
Fortunately I researched this earlier this year and found some suggestions on how to implement random numbers in HDL:

See http://www.gaussianwaves.com/2015/06/how-to-generate-awgn-noise-in-matlaboctave-without-using-in-built-awgn-function/ for a code outline.
The difficult part there is that randn() is not implemented for HDL. The Answer I link to above contains references to two HDL implementations of random number routines, which you could use to generate the normally distributed random numbers.
