We propose FSK/ASK re-modulation WDM-PON with coherent receiver. Apparent BER improvement is obtained by utilizing FSK image rejection receiver, especially for long distance transmission. Parameters in image rejection receiver which affect the system performance are analyzed. Results show that the presented scheme is promising in super long reach access network.
Since mobile communication has been well developed, high quantity services is also expected by mobile users, so repeaters, which amplify the coverage of both analog and digital communication base stations, have been popularly used by mobile communication providers. A repeater is a device that receives a digital or analog signal on an electromagnetic or optical transmission medium and regenerates the...
This paper aims to find the most optimal Grey-Fuzzy routing algorithm within multinomial time about the NP-complete problem of multi-objective optimization QoS routing. With the help of Grey-Fuzzy theory, this algorithm achieves an O(mn) time complexity through integrating the QoS metrics to a Grey-Fuzzy synthetic attribute according to its membership degree and grey degree. Our algorithm can use...
