摘要： Communications between a terminal and a terrestrial base station are established. The terrestrial base station receives a request to monitor a satellite base station from the terminal. The terrestrial base station grants the request and receives monitoring information for the satellite base station corresponding to the request. Granting of the request may include suspending transmission from the terrestrial base station to the terminal for a period of time sufficient to allow the terminal to request the monitoring information from the satellite base station and receiving monitoring information may include receiving the requested monitoring information at the terrestrial base station via a communications path not including the terminal. Suspending transmission from the terrestrial base station to the terminal may be followed by resuming transmission to the terminal before receiving the monitoring information at the terrestrial base station. The communications path not including the terminal may include a terrestrial Access Service Network Gateway serving the terrestrial base station and a satellite Access Service Network Gateway serving the satellite base station. Handover techniques are also described.

摘要： A system for optical communication forms a family of orthogonal optical codes modulated by a data stream. The orthogonal codes are formed by creating a stream of evenly spaced-apart pulses using a pulse spreader circuit and modulating the pulses in amplitude and/or phase to form a family of orthogonal optical code words, each representing a symbol. A spreader calibration circuit is used to ensure accurate timing and modulation. Each code word is further modulated by a predetermined number of data bits. The data modulation scheme splits a code word into H and V components, and further processes the components prior to modulation with data, followed by recombining with a polarization beam combiner. The data-modulated code word is then sent, along with others to receiver. The received signal is detected and demodulated with the help of a symbol synchronization unit which establishes the beginning and end of the code words. A polarization mode distortion compensator at the receiver cooperates with a state of polarization compensator at the transmitter to mitigate polarization distortion in the fiber.

摘要： A system for optical communication send optical signals over a plurality of wavelength channels. Each wavelength channel comprises a number of orthogonal subchannel frequencies which are spaced apart from one another by a predetermined amount. Each of the subchannel frequencies is modulated with data from a data stream. The data modulation scheme splits a subchannel frequency code into H and V components, and further processes the components prior to modulation with data. The various data-modulated subchannels are then combined into a single channel for transmission. The received signals are detected and demodulated with the help of a symbol timing recovery module which establishes the beginning and end of each symbol. A polarization mode distortion compensation module at the receiver is used to mitigate the effects to polarization more distortion in the fiber.
