ABSTRACT:
A communication device for receiving and transmitting OFDM signals in a wireless communication system, in which each OFDM signal is composed of a plurality of subcarrier signals each being assigned to a respective transmission channel of said communication system, including a diversity antenna unit including a plurality of antenna elements; an examination unit adapted for examining, individually for each antenna element, at least one subcarrier signal of an OFDM reception signal received by a respective one of the antenna elements and for gaining, from the result of such subcarrier signal examination, attenuation information on attenuation properties of at least some of the transmission channels associated to the respective antenna element; and an amplitude adjustment unit adapted for adjusting, individually for each antenna element, the amplitude of at least one subcarrier signal of an OFDM transmission signal to be transmitted from a respective one of said antenna elements.
