Apparatus and methods for generating an accurate estimate of a time of receipt of a packet

A first communication device generates a plurality of samples from a sampled signal. The sampled signal corresponds to a first sampling frequency, and the plurality of samples correspond to a second sampling frequency that is greater than the first sampling frequency. Additionally, the sampled signa...

Beschreibung
Zusammenfassung:	A first communication device generates a plurality of samples from a sampled signal. The sampled signal corresponds to a first sampling frequency, and the plurality of samples correspond to a second sampling frequency that is greater than the first sampling frequency. Additionally, the sampled signal corresponds to a transmission signal transmitted from a second communication device to the first communication device. The first communication device generates a correlation signal using the plurality of samples, and uses the correlation signal to generate an estimate of a time at which the transmission signal was received at the first communication device.
