    摘要： Methods and systems for contingency communication are disclosed. In one embodiment, a method for providing emergency services may be performed by a portable device operating in a communication system. In an embodiment, the method for providing emergency services includes operating in at least one of a plurality of modes. A stress mode may be entered from a normal mode in response to receiving a beacon signal indicating an emergency status. An indication may be provided on the portable device regarding the emergency status via an audio, visual, or mechanical user interface during the stress mode. An acknowledgement signal may be transmitted in response to the beacon signal.

    摘要： A broadband wireless communication system, wherein both Multi-Carrier (MC) and Direct Sequence Spread Spectrum (DSSS) signals are intentionally overlaid together, in both time and frequency domains. The overlaying mitigates the weaknesses of each technique. The MC signal carries the broadband data signal and takes advantage of its high spectral efficiency, while the DSSS signal is used for special purpose processing such as initial random access, channel probing, and short messaging, where properties such as signal simplicity, self synchronization, and performance under severe interference are desired. The methods and techniques ensure that the MC and the DSSS signals are both distinguishable and that the interference between the overlaid signals is minimized to have insignificant impact on the expected performance of either signal.
