Use floating-point numbers in the "MatlabOptiSysBER.m" example

[Shayma Akram]

Hello,

In this example “MatlabOptiSysBER.m” they use this code:

% Generate the matrix with integers to be transmitted
IntSignalin = randint(NrOfInt,NrFrames,2^M-1);

to generate the input signal.
in may case, I have a matrix of floating-point numbers, my questions are:

(1) Is it possible to use it instead of IntSignalin[]??

(2) In the previous example, the integer numbers have been converted to binary by using this code:

% Converte integers to binary numbers
for swint = 1:NrFrames
BinarySig(swint,:) = reshape( dec2bin(IntSignalin(:,swint)) , NrOfInt * M, 1 );
end

In my case, to generate “BinarySig[]”, do I have to convert floating-point matrix to binary based on IEEE Standard 754 or there are other methods??

You could but you would need to use a different component. Either a matlab component or some type of measured electrical/optical signal.

You will notice from the layout of the OptiSystem project that the Binary Sequence generator is loading a file. This file is generated by the Matlab code, so you can understand why you can’t use a double type format in the saved file.
