Communication device and method for radio communication

A communication device, comprising:

• a transmitter configured to transmit a first signal, a third signal, and a projected signal;
• and
• a circuit configured to determine the projected signal based on an estimated signal state information such that an energy of a shaped projected signal is smaller than an energy of a shaped signal,
• wherein a signal state information is based on the first signal and a second received signal that is received by a receiver of a second communication device,
• wherein the estimated signal state information is determined based on an interpolation of a first received signal that is received by a first communication device and a third received signal that is received by a third communication device,
• wherein the first received signal is received based on the first signal,
• wherein the third received signal is received based on the third signal,
• wherein the estimated signal state information is an estimate of the signal state information,
• wherein the shaped projected signal is the projected signal received by the receiver of the second communication device and filtered by a filter of the second communication device,
• wherein the shaped signal is the second received signal filtered by the filter of the second communication device.
