Simple Codes Concept:
How Codes Can Be Used




Let us consider the following steps or activities at a given transmitter location:
Step 1 |An arbitrary data sequence di(t) generated by a digital source.
Step 2 |Now generate an arbitrary Code sequence ci(t).
Step 3 |Add these two sequences Modulo-2 (Exclusive-OR gate) as shown in step 3 above.
Let's transmit the output of the Exclusive-OR gate to a distant receiver (We'll assume there is no propagation delay here).
