In these transmission systems, neither the phase nor frequency of the optical signal carries information - only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored.\u003c\/p\u003e \u003cp\u003e\u003c\/p\u003e \u003cp\u003eAs a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics: \u003c\/p\u003e \u003cp\u003eThe transmitter and receiver for phase-modulated coherent lightwave systems \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e \u003cp\u003eMethod for performance analysis of phase-modulated optical signals \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e \u003cp\u003eDirect-detection DPSK signal with fiber nonlinearities, degraded by nonlinear phase noise and intrachannel effects \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e \u003cp\u003eWavelength-division-multiplexed direct-detection DPSK signals \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e \u003cp\u003eMulti-level phase-modulated optical signals, such as the four-phase DQPSK signal \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e \u003cp\u003e\u003c\/p\u003e \u003cp\u003eGraduate students, professional engineers, and researchers will all benefit from this updated treatment of an important topic in the optical communications field. \u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45274452164759,"sku":"9781441937377","price":8079.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781441937377.webp?v=1769279967","url":"https:\/\/atlanticbooks.com\/products\/phase-modulated-optical-communication-systems-9781441937377","provider":"Atlantic Books","version":"1.0","type":"link"}
