The multi-channel radio frequency module with frequency division of data reception and transmission contains at least two radiating elements; at least two received signal filters and at least two transmitted signal filters, each of which is tuned to pass the received and transmitted signal accordingly in a certain frequency band; at least two radio frequency receivers, each of which is connected to the received signal filter; and at least two radio frequency transmitters, each of which is connected to the transmitted signal filter. Radiating elements having two input ports; one of which is connected to the received signal filter, and the other to the transmitted signal filter, the passbands of these filters being non-overlapping. Application of the invention allows the miniaturization of the microwave PtP communication station while simultaneously providing efficient electronic beam scanning with small signal loss for beam switching and high isolation between receivers and transmitters.

The present invention generally relates to the field of electrical communication and more specifically to apparatuses and methods of phase noise mitigation for signal transmission in wideband telecommunication systems. The method for compensation of the phase noise effect on the data transmission through a radio channel is based on a possibility to present the phase noise of a reference oscillator like a random process where the main spectral density is concentrated in the low-frequency region. Therefore, the number of estimated parameters can be reduced many times to several low-frequency spectral components instead of a direct estimation in the time domain. The advantage of the method is an improvement of the estimation accuracy and a reduction of the computational complexity.
