    • Methods and systems for secure communication include assigning data streams to respective orthogonal sub-carriers according to random number information at a transmitter. The data streams are modulated onto the respective orthogonal sub-carriers before the orthogonal sub-carriers are transmitted. The random number information is transmitted on a second medium, separate from the transmission medium. The orthogonal sub-carriers are received from the transmission medium at a receiver, while the random number information is received from the second medium at the receiver. The orthogonal sub-carriers are associated with data streams using the random number information and demodulated to produce data for the associated data stream.
    • 用于安全通信的方法和系统包括根据发射机处的随机数信息将数据流分配给各个正交子载波。 在发送正交子载波之前,将数据流调制到各个正交子载波上。 在与传输介质分离的第二介质上发送随机数信息。 在接收机处从传输介质接收正交子载波,而在接收机处从第二媒体接收随机数信息。 正交子载波与使用随机数信息的数据流相关联并被解调以产生用于相关联的数据流的数据。

    • A differential delay detection system and method includes an optical splitter to split an incoming optical signal between a first path and a second path. The first path includes a cross-polarization interferometer configured to separately generate polarization independent outputs using split paths and to generate cross-polarization interference outputs, and a polarization demultiplexer configured to combine the polarization independent outputs and the cross-polarization interference outputs from the cross-polarization interferometer with updated coefficients received from the second path to remove the cross-polarization mixed signals. The second path includes a training signal receiver configured to compute the updated coefficients and output the updated coefficients to the polarization demultiplexer.
