This course is a sequel to Principles of Communication-Part I and covers fundamental concepts of communication systems, especially focusing on various aspects of modern digital communication systems. However, all the modules in this course will be independent of the previous course and hence students who could not participate in Principles of Communication-Part I will also be able to follow the course. Beginning with the basic theory of digital communication systems pertaining to pulse shaping, modulation and optimal detection, the course will also cover several important digital modulation techniques such as Binary Phase Shift Keying (BPSK), Frequency Shift Keying (FSK), Quadrature Amplitude Modulation (QAM), M-ary Phase Shift Keying (M-PSK) etc. Other fundamental concepts such as Information Theory, Channel Capacity, Entropy Coding and Error Control Coding will be dealt with in the later parts of the course.This course is suitable for all UG/PG students and practicing engineers/ managers who are looking to enhance their knowledge of the fundamental principles underlying various communication systems as well as students preparing for their college/ university/ competitive exams.INTENDED AUDIENCE: Students, practicing engineers, technical and non-technical managers of telecomm companies, students preparing for competitive exams with communication engineering subject.PRE-REQUISITES: Basic knowledge of - Probability, CalculusINDUSTRIES SUPPORT: Most companies in wireless communications area should find this useful. Examples are Qualcomm, Broadcom, Intel etc.
