End-to-End Systems


Today's end-to-end systems must make use of a number of recent and advanced techniques in order to comply with the demands of today's video services to consumers. To meet transmission demands, end-to-end systems must utilize every available Hertz of bandwidth in the electromagnetic spectrum.

Advanced Digital Modulation Techniques

Digital data is usually thought of as strings of ones and zeros. Relating this to analog video signals, this could be appropriately called baseband digital data. A variety of complex modulation schemes can encode digital data signals for transport. These modulation schemes serve to pack more data per Hz of the spectrum. Spectral efficiency measures the number of bits packed into each ...
