摘要： An optical transceiver includes N transmitters each transmitting one of N transmitted optically bound channels; a clock forwarding mechanism to transmit a transmitted optical clock signal to an opposing optical receiver; N receivers each receiving one of N received optically bound channels; and a clock recovery mechanism to receive a received optical clock signal from the opposing optical transmitter. A method and photonically integrated system are also disclosed. The optical transceiver, method, and system optimize system design of WDM highly parallelized transceivers with optical bound channels, a simplified clocking architecture, and boosted receiver sensitivity. The optical transceiver, method, and system include clock recovery followed by data recovery and can utilize integrate-and-dump optical receivers with a recovered clock.

摘要： Described herein is a method and system for estimating a time-varying multipath communication channel. The system comprises a receiver for receiving a signal comprising a data packet transmitted over the multipath communication channel. The system also comprises a frequency-domain channel estimator that generates a frequency-domain channel estimate based on the received signal. The system further comprises a time-domain channel modeller that receives the frequency-domain channel estimate and generates an estimate of parameters in a time-domain model of the multipath communication channel. The model characterizes the multipath communication channel as a delay line with a plurality of taps, each tap having tap parameters defining a delay, a Doppler and a gain for the tap. The tap parameters are constant over the data packet.

摘要： The invention concerns an optical transmission system and method providing for transmission of a downlink and uplink data traffic between a central terminal (15) and a plurality of client terminals (17) being interconnected by means of a passive optical access network (5), including the following steps: transmitting data borne by an amplitude-multiplexed light signal (S) comprising a plurality of amplitudes and having a single wavelength to the plurality of client terminals (17); transforming by spectral shifting, the single wavelength of said light signal (S) sent by said central terminal (15) into a plurality of wavelengths, based on the plurality of amplitudes thus forming a wavelength division multiplexed light signal, so that said data are received by said plurality of client terminals (17) based a plurality of light signals (S1,, SN) having a plurality of different wavelengths, each of said client terminals (17) receiving the data which are associated therewith based at least on one specific wavelength; and routing said downlink and uplink traffic between said central terminal (15) and the client terminals (17).

摘要： Systems and methods for the communication and recovery of supplementary data encoded in the primary information transmitted from a source to a receiver for both audio and television transmissions. The method includes modulating a carrier signal with the supplementary data using a spread spectrum approach and demodulating the carrier signal to recover the embedded supplementary data.

摘要： Procédé de transmission dans un système de radiocommunication du type à accès multiple, à ressources de transmission orthogonales, ce procédé étant caractérisé en ce que, pour un nombre M d'utilisateurs supérieur au nombre N de ressources de transmission de ce système :
au moins une desdites ressources de transmission (s 1 , ..., s 8 ) est partagée à un instant donné par au moins deux utilisateurs,
les utilisateurs qui partagent une ressource de transmission changent au cours du temps, de manière à répartir le mieux possible entre les différents utilisateurs (u 1 , ..., u 9 ) la dégradation de rapport signal à bruit résultant dudit partage,
ladite dégradation de rapport signal à bruit est en outre réduite en différenciant, par leur niveau d'émission, les signaux correspondant à des utilisateurs partageant une même ressource à un instant donné.摘要翻译： 该系统通过在周期性的基础上共享资源来确保所有用户的最佳信噪比，从而使任何信道衰减的影响在其中传播。 该过程在具有正交传输资源的多址无线电通信系统中提供传输。 用户数（M）可能大于可用传输资源的数量（N）。 至少一个传输资源（s1至s8）在给定时刻由至少两个用户共享。 在时间上共享资源变化的用户，以便分享不同用户（u1-u8）之间信噪比的降低。 信号噪声比的降低通过根据它们的传输水平根据在给定时刻共享特定资源的用户对应的信号进行微分来进一步降低。
