Abstract
An Orthogonal Frequency Division Multiplexing, OFDM, transmitter comprises a signalling data generator () which generates a set of data symbols indicative of physical layer characteristics of data transmissions from the OFDM transmitter (). A first symbol generator () and second symbol generator () generates a first and second OFDM signalling symbol by allocating the set of data symbols to subcarriers. The allocation of the physical layer data symbols to subcarriers is different for the first OFDM signalling symbol and the second OFDM signalling symbol. A data packet generator () and transmitter () generate a data packet and transmit this to an OFDM receiver (). The OFDM receiver () determines the physical layer data symbols by combining the data symbols of corresponding subcarriers of the first and second OFDM signalling symbols and uses the resulting information to decode the user data of the data packet.
