discrete memoryless channel in information theory ? THE DISCRETE MEMORYLESS CHANNELS (DMC)             In this section, let us discuss different aspects related to discrete memoryless channels (DMC). 9.8.1. Channel Representation             A communication channel may be defined as the path or medium through which the symbols flow to the receiver end. A discrete mamoryless channel… Continue reading »

ENTROPY | what is properties of entropy in information theory (AVERAGE INFORMATION)

what is properties of entropy in information theory ? ENTROPY (I.e., AVERAGE INFORMATION) (i) Definition             In a practical communication system, we usually transmit long sequences of symbols from an information source. Thus, we are more interested in the average information that a source produces than the information content of a single symbol. In order… Continue reading »
