Channel Encoder and Decoder Explained | CRC Example + Error Detection in Digital Communication
In this video, we explore Channel Encoder and Channel Decoder in digital communication systems and how they work together to ensure reliable data transmission over noisy channels. You will learn how the encoder adds redundancy to protect data, and how the decoder uses it to detect errors at the receiver side.
We also go through a simple CRC example (using data 1101 and generator 101) to clearly demonstrate how error detection works in practice. This helps you understand step by step how transmitted data can be verified and how systems respond when errors are detected.
Topics covered:
Channel Encoder and Decoder basics
Noisy channel and bit errors
Types of channel coding (Block, Convolutional, Modern Codes)
CRC example for error detection
Retransmission concept (ARQ)
This video is ideal for beginners in digital communication, RF systems, and networking fundamentals.
