ABSTRACT:
In a method for generating a periodic training signal comprising cyclically expanded training symbols for a transceiver which transmits data via a data transmission channel using a predetermined number N of modulated carrier signals an address pointer for addressing a starting address in a memory is calculated for each training symbol on the basis of cyclic expansion parameters and, starting from the calculated starting address, 2*N stored samples of a transformed training symbol are read cyclically from the memory.
