对DP-QPSK(偏振复用正交相移键控)调制和相干接收技术在低速系统中的应用进行了研究,实现了2.67Gbit/s速率的实时传输。实验结果表明,DP-QPSK调制和相干接收技术对无中继ULH(超长跨距)光传输系统的OSNR(光信噪比)容限有优化作用。

In this letter,we propose a hybrid analog/digital detection algorithm,the Correlated In-terference Cancellation(CIC) algorithm,for Impulse Radio Ultra-WideBand(IR-UWB) system.The CIC algorithm correlates received signal with its delayed versions in the analog domain and samples the correlation output at the symbol rate.The symbol rate samples are processed in the digital domain to perform interference cancellation.Therefore,CIC works for high data rate systems with heavy In-terSymbol Interference(ISI).Simulation results show that CIC achieves good performance in typical UWB channels. 展开更多
