A shift of 1/B*N between the first modulated data stream and each of its N−1 subsequent modulated data streams is generated using time delay or phase shifting and then the first modulated data stream and its shifted subsequent modulated data streams are combined into a composite multilevel signal with up to N levels and the composite multilevel signal is transmitted to a receiving end of the channel. At the receiving end, the composite multilevel signal is sampled N times during each bit-time, in order to obtain a vector with N elements at each time, such that each element has N+1 possible values and corresponds to the order of a sample. Each of the N modulated data streams are reconstructed by vectorial MLSE, preformed for each element by calculating the joint conditional PDF."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for increasing the capacity of a data communication channel","description":"Method for efficiently increasing the capacity of an optical channel which can operate in a given data rate B, by generating N modulated data streams with a bit rate of B/N and a bit-time of N/B at th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8483570","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
