What is source code in digital communication?
Source coding: The source encoder converts information waveforms to bits, while the decoder converts bits back to waveforms. The block diagram of source coding is depicted in Fig. 3. 2. Channel coding: The channel encoder converts bits to signal waveform, while the decoder converts received waveform back to bits.
What are the source coding techniques?
Based on the fundamentals of information and rate distortion theory, the most relevant techniques used in source coding algorithms are described: entropy coding, quantization as well as predictive and transform coding.
What is source coding list out the needs for source coding in digital communication?
source coding (source compression coding) The use of variable-length codes in order to reduce the number of symbols in a message to the minimum necessary to represent the information in the message, or at least to go some way toward this, for a given size of alphabet.
What is the role of source coding and channel coding in communication system?
The goal of source coding is to represent a source with the lowest possible rate to achieve a particular distortion, or with the lowest possible distortion at a given rate. Channel coding adds redundancy to quantized source information to recover channel errors.
