<p>The method involves modifying user data (52) to be transmitted for forming a test data (50) at a transmitter, and forming another test data from the former test data and the unmodified user data. The user data and two test data are transmitted to a receiver, and the unmodified transmitted user data and the former test data are verified using the latter test data at the receiver. The user data is verified using the former test data, where the user data is modified corresponding to the modification for forming the former test data and the modification takes place by expanding the user data. An independent claim is also included for a system for detecting an error during transmission of data.</p> |
