High power signal communications within a power limit

A radio frequency (RF) communication method, the method comprising:

• receiving an RF signal by a wideband receiver;
• processing the received RF signal by a wideband receive signal path, processing a transmit RF signal to be transmitted by a wideband transmit signal path;
• transmitting the transmit RF signal at a selected transmit frequency and a selected transmit polarization by a wideband transmitter;
• controlling a plurality of beam forming circuits for performing signal processing and waveform generation;
• and
• maximizing an effective radiated power (ERP) of the communication system within a predetermined ERP limit by switching the wideband transmitter between at least one of multiple transmit frequencies and multiple transmit polarizations to form an aggregate, time-averaged signal as the transmit RF signal, wherein maximizing the ERP of the communication system within a predetermined ERP limit further comprises:
• determining a time to switch the selected transmit frequency, as a function of a transmission power of the wideband transmitter and the predetermined ERP limit, determining whether the wideband transmitter is using different polarization schemes, when it is the time to switch the selected transmit frequency;
• switching the wideband transmitter to a new transmit frequency separated from the selected transmit frequency by a predetermined bandwidth, when it is determined that the wideband transmitter is not using different polarization schemes;
• determining a time to switch the selected transmit polarization, as a function of a transmission power of the wideband transmitter and the predetermined ERP limit, when it is determined that the wideband transmitter is using different polarization schemes;
• switching the wideband transmitter to the new transmit frequency, when it is not the time to switch the selected transmit polarization;
• and
• switchinq the wideband transmitter to a new transmit polarization, when it is the time to switch the selected transmit polarization, to transmit the aggregate, time averaged low power signal at rotating polarizations and frequencies, as the transmit RF signal.
