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.
Claims8
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;
- said method comprising the steps of:
- calculating, for each of said training symbols, an address pointer for addressing a starting address in a memory on the basis of said cyclic expansion parameters;
- and
- starting from said calculated starting address, reading cyclically from said memory 2*N stored samples of a transformed training symbol.
An apparatus for generating a periodic training signal, which comprises cyclically expanded training symbols, for a transceiver which transmits data via a data transmission channel using a predetermined number N of modulated carrier signals;
- said apparatus comprising:
- a memory for storing 2*N samples of a transformed training symbol;
- and
- a control logic unit calculating, for each of said training symbols, an address pointer for addressing a starting address on the basis of cyclic expansion parameters and cyclically reading said samples stored in said memory, starting from said calculated starting address.
