Description: Walsh-Hadamard codes are mutually orthognal codes,
thus when used in synchronous CDMA, the interference between users is zero.
This programm generates Walsh-Hadamard codes and also checks the orthogonality.
You can change the code length by changing value of "code_length" at the top of program
