Channel Coding: Part 2: Convolutional Codes and Reed–Solomon Codes

A block diagram is given where an information source is formatted into message symbols as digital inputs - m subscript i, which then enters the source encoding phase as digital input, then enters channel encoding phase and transforms into channel symbols as channel input. The channel inputs then pass through the multiplex phase from other sources. The channel symbols coming out of the multiplex phase passes through the pulse modulate phase and become digital baseband waveform - g subscript i baseline of t, and then passes through bandpass modulating phase where it ...
