What is the purpose of source coding?

The aim of source coding is to represent information as accurately as possible us- ing as few bits as possible and in order to do so redundancy from the source needs to be removed.

Does source coding reduce redundancy?

Redundancy reduction is accomplished by a source encoder, which often operates in conjunction with the analog-to-digital converter.

Why channel coding reduces the bandwidth efficiency of the link?

Channel coding adds redundant bits to the transmitted bit stream, which are used by the receiver to correct errors introduced by the channel. This allows for a reduction in transmit power to achieve a given target BER and also prevents packet retransmissions if all the bit errors in a packet can be corrected.

What is the purpose of source coding and channel coding?

The channel coding in a communication system, introduces redundancy with a control, so as to improve the reliability of the system. The source coding reduces redundancy to improve the efficiency of the system.
