PPT-UNIT-5 CHANNEL CODING 1

Convolutional codes map information to code bits sequentially by convolving a sequence of information bits with generator sequences A convolutional encoder encodes K information bits to . The bit stream representation of a symbol is called the codeword of that symbol Di64256erent error control mechanisms Linear Block Codes Repetition Codes Convolution Codes brPage 2br Linear Block Codes A code is linear if two codes are added using m FEC Basic Idea. Send redundant data . Receiver uses it to detect/correct errors. Reduces retransmissions/. NAKs. Useful when RTT is high. Types of FEC . Two types of FEC. Block codes (works on blocks/packets).
