Abstract: A cyclic prefix which duplicates some samples of a terminal portion of a symbol in an OFDM data stream and which is invariant in pilot tones can be detected in the presence of signals having higher levels of noise and broadcast signals by autocorrelation with one of two selected “lags”.

A far stronger autocorrelation is found when the lag is equal to the sum of the FFT length and the length of the cyclic prefix and applied to pilots in the data stream. Overbuilt systems can be distinguished from a system of interest by use of pilots that do not coincide in frequency with a pilot of an overbuilt system.

Abstract: A route-tracing application can measure the performance of a path in a named-data network using trace agents deployed across various network nodes. During operation, a network node can process a route-tracing Interest by performing a lookup operation in a forwarding information base (FIB) using the Interest's name, in which a respective FIB entry may map the name to a forwarding rule. If the FIB does not include an entry for the Interest's route-tracing name, a trace agent at the network node determines one or more outbound interfaces for the route-tracing operation based on the Interest's name, and creates new route-tracing FIB entries that each maps the Interest's name to a forwarding rule for the determined interfaces. The network node returns a Content Object that satisfies the Interest, in which the Content Object includes the names of the new FIB entries, as well as performance information for the path.
