Hi Acosta, I am not going to do your homework assignment for you. If you want some help, you need to make an effort to figure it out for yourself. I have given you enough to get started. Please let me know what you have tried on your own, and what _specific_ questions you have.

Here is another hint:
Suppose you have a series of randomly generated symbols drawn from the set of integers { 0, 1, 2, 3 }, and you would like to map them to the integers { -3, -1, +1, and +3 }, what mathematical formula could you use to compute this mapping?
HTH.
Rick

You need to convert numbers from a binary representation (base 2) to a decimal representation (base 10). That is why I suggested looking at the bin2dec function.
If you break up the binary string into blocks of 2 bits each, you can use the bin2dec function to convert them to integer-valued numbers, each of which is an element of the set { 0 1 2 3 }. For example:
b = '10';
x = bin2dec(b);
disp(x)
will return the value of x as 2.
Likewise, if you break the binary string into blocks of three bits each, you will end up with integers in the set 0 ... 7 inclusively.
