Modulation and CodingSpeaker: Abhishek Roy – San Francisco, United States
Topic(s): Networks and Communications
AbstractIn a digital communication system, the source to be transmitted is discrete both in time and amplitude. Digital information carrying signals must be first converted to an analog waveform prior to transmission. At the receiving end, analog signals are converted back to a digital format before presentation to the end user. The conversion process at the transmitting end is known as modulation. The receiving end is known as demodulation or detection. Similarly channel codings are required in wireless communication systems to cope up with channel errors and signal fading. In this lecture, we provide a tutorial on basics of modulation and conding schemes, with an additional focus on wireless systems. We will cover charecteristics of electromagnetic signals, concepts of data, signal, analog transmission of digital data and digital transmission of analog data.
