    摘要:

    光纖網(wǎng)絡(luò )的通信質(zhì)量受到云數據調度均衡性影響很大,為了改善光纖網(wǎng)絡(luò )通信質(zhì)量,提高網(wǎng)絡(luò )中云數據傳輸的吞吐量和保真率,通過(guò)云數據并行調度,實(shí)現云數據傳輸均衡,提出一種基于自適應判決反饋均衡的光纖網(wǎng)絡(luò )云數據并行調度模型;構建光纖網(wǎng)絡(luò )通信的傳輸信道模型,采用最小均方誤差估計方法進(jìn)行光纖網(wǎng)絡(luò )的量化融合估計,運用匹配濾波檢測器進(jìn)行云數據中的干擾濾波處理,結合自適應判決反饋均衡方法進(jìn)行信道均衡,在均衡的信道中對濾波輸出的云數據進(jìn)行并行調度和多線(xiàn)程輸出調制;仿真結果表明,采用該方法進(jìn)行光纖網(wǎng)絡(luò )中的云數據并行調度的均衡性較好,輸出數據的保真率較高,誤碼率較低,改善了光纖網(wǎng)絡(luò )的整體性能。

    Abstract:

    The communication quality of the optical fiber network by cloud data scheduling greatly influence the balance, in order to improve the quality of optical fiber communication network, improve network cloud data transmission throughput and fidelity rate scheduling in parallel by the cloud data, cloud data transmission is proposed based on adaptive equalization, decision feedback equalization of optical fiber network cloud data parallel scheduling model construction. The transmission channel model of optical fiber network communication, quantitative estimation of optical fiber network by using the minimum mean square error estimation fusion, was treated by interference filter cloud data matched filter detector, the adaptive decision feedback equalization method for channel equalization, channel equalization in cloud data to the filter output of the parallel scheduling and multi thread output modulation. The simulation results show that using the method of parallel scheduling in cloud data in the fiber network is balanced well, the fidelity of the output data is high, and the bit error rate is low, which improves the overall performance of the optical network.
