Abstract: Many of todays sensor nodes exhibit special transmission errors. These errors are due to some common hardware components being used, particularly the so-called UART (serial communication) circuits that interconnects radio transceivers and the CPUs. UARTs generate start-, data- and stop-bits. As long as the state machine at the sender and the receiver is synchronized, even single bit errors can often be corrected by Forward Error Correction (FEC). However, once one or several bits are missed, the state machine at the receiver side will get out of sync so that data bits are misinterpreted as start- or stop-bits and vice versa, rendering the entire remaining communication useless. In this paper, we will devise a periodic resync scheme that enables the receiver to catch up on a data stream even in case of skipped bits. In noisy environments as well as for weak senders, we can improve the overall data throughput significantly.
