Orthogonal Codes

Orthogonal codes are patterns used in communication systems to distinguish multiple signals sharing the same medium, such as in wireless networks or CDMA technology. They are designed so that when signals encoded with different orthogonal codes are combined, they do not interfere with each other; mathematically, their cross-correlation is zero. This ensures that each signal can be accurately separated and identified at the receiver, improving clarity and efficiency. Think of orthogonal codes as unique, non-overlapping "passcodes" that allow multiple conversations to happen simultaneously without interference.
