Whether from the transmitter mast to the smartphone or from the Wi-Fi router to the laptop - data is constantly being transmitted everywhere. Errors can easily creep in - which is why sophisticated correction processes are used during data transmission. They add certain redundancies to the actual data record. If something is lost during transmission, the data can usually be reconstructed from the rest of the data record. In his work, Sven Jandura (18) from Dresden looked at one of the most common correction methods, the so-called RS codes. He developed a complex mathematical analysis method to find out how often transmission errors still occur. This makes it possible to specify a residual error probability without having to measure it experimentally.
