Over two-dimensional Folded Optical Orthogonal Coding (FOOC) network, a simple threshold detection scheme is illustrated to detect the number of simultaneous network users and to adjust the detection threshold value instantaneously. A special wavelength called pilot wavelength is added into the original transmission patterns of every network user. Consequently, by adjusting the detection power threshold to the optimum threshold value, we can decrease the bit error rate (BER) and improve the system performance for the discussed two- dimensional optical code-division multiple-access (2D-OCDMA) network. Compared with conventional network system adopting prime codes or modified prime codes, the proposed FOOC network with pilot wavelength threshold detection shows an enhanced BER performance and supports more simultaneous network users. At the receiver, we can acquire the number of simultaneous network users from the power of the pilot wavelength.

Приемы комического в языке произведений П.Г....
My ow view was ha he had go he s uff, by s riki g like glue o he fi es. Five quid here, five quid here – you ca see how i would mou up over a period of years. Этим вклиниванием – a lis – герой подчеркивает свое недоверие к честности мирового судьи. Комичность ситуации тем яснее, что говорящий был оштрафован, и, как они считает, несправедливо, этим судьей. Среди вводных конструкций, встречающихся у Вудхауза, большинство составляют вводные предложения. Их семантико- стилистическая функция представляется нам следующей: для писателя вводные предложения – прекрасное средство воплощения сатирического замысла, достижения определенного юмористического эффекта, что составляет второй план повествования. Вот, к примеру, как использование вводных предложений плюс прием структурного и стилистического повтора задает тон всему тексту целиком. На протяжении романа “ he Code of he Woos ers” герой, от лица которого идет повествование, постоянно ловит себя на том, что он не уверен в правильности и грамотности своей речи.
