Distributed Coherent Group Communications
MILCOM 2018 - 2018 IEEE Military Communications Conference (MILCOM), 2018Wireless communication networks need to support high data rate, low power consumption and extended connectivity over long distances, which may not be feasible with point-to-point transmissions. This paper presents the distributed coherent group communication solution to achieve high power gain, which is in turn translated to improvements in ...

Coherent Nd:Yag Laser Communications
SPIE Proceedings, 1987The majority of today's optical communication systems employ non-coherent detection or what is commonly referred to as direct detection. However, recent advances in technology have made the concept of coherent optical detection feasible. A properly designed coherent system can offer a significant improvement in receiver sensitivity.

Coherent soliton communication lines
Journal of Experimental and Theoretical Physics, 2014The data transmission in coherent fiber-optical communication lines using solitons with a variable phase is studied. It is shown that nonlinear coherent structures (solitons) can be applied for effective signal transmission over a long distance using amplitude and optical-phase keying of information. The optimum ratio of the pulse width to the bit slot

Broadband Coherent Communication System
IETE Technical Review, 2003During the last few years, there has been an increasing demand for high-speed data transmission. Although, fiber optics technology has matured already for high data transport, however, for spaces lacking the fiber infrastructure, wireless technologies are becoming the medium of choice for broadband networking. The first investigations on optoelectronic

Coherent Optical Communication Systems
2011The rapid evolution of long-haul optical communications systems, witnessed in the last five years, is due to the gradual adoption of spectrally efficient, multilevel modulation formats, in conjunction with polarization division multiplexing (PDM) and coherent intradyne detection assisted by digital signal processing (DSP).

Coherent fiber communications analyzer
Eletrónica e Telecomunicações, 2012This paper addresses an coherent fiber communication analyzer with digital signal processing (DSP). First we make an overview of the investigations that are being conducted at Instituto de Telecomunicações (IT) in the coherent communications area and then introduce the coherent receiver used in the IT laboratory.
