Abstract
Systems and methods of providing error tolerant robust simplex wireless data for systems employing time correlated data transfer are provided. In one embodiment, a system comprises: sensors that produce samples of time correlated data; and a node coupled to the sensors by a wireless link. The link comprises a primary stream for simplex transmission of data packets, and a secondary stream for simplex transmission of delayed data packets, the delayed data packets a delayed retransmission of the time correlated data. When the node receives a first data packet from a first sensor via the primary stream, the data receiving node check validity. When the first data packet is corrupted, the node validity checks a second data packet received via the secondary stream. When both packets contain corrupted data, the node builds a reconstructed plurality of sequential time correlated data samples based on non-corrupted data samples from within the data packets.
