Abstract
Systems and methods providing resampling of a sampled data transmitted through a communication channel. Reliable resampling is provided even when original data samples are lost or reordered during transmission through the network. In one embodiment, a receiver associates each received data sample with a respective sampling time instant. The received data may include index values that associate the received data samples with respective sampling time instants. In other embodiments, the received data includes time stamps with encoded sampling time instant information. In another embodiment, arrival time instants are used to correlate the received data samples with their respective sampling time instants. The receiver then uses the sampling time information to select data samples corresponding to resampling time instants. If needed, the receiver uses interpolation to generate resampled data points corresponding to the resampling time instants.
