SOURCE CODING AND TRANSMISSION TECHNIQUES

As previously described, one of the most important advantages of digital transmission relies on the ability to perform regeneration, although at the cost of a higher signal bandwidth, as compared to analog signals. Regeneration of signals allows partially removing the effects of channel impairments, such as noise, interference, attenuation, or distortion.

Chapter 1 stated that, depending on whether signals are transmitted in analog or in digital form and assuming that the source data is digital, such signals require passing through a process of modulation* or line coding, respectively (see Figure 6.1). This is performed using a specific modulation scheme or digital coding that aims to optimize and ...
