Abstract: The present disclosure relates to communications technologies, and provides a single polarized ME dipole and a basic radiator of a phased array antenna for millimeter wave or above frequency band. The radiator is an “array of the ME dipoles” with higher dielectric constant, and can be manufactured with the multilayer PCB or LTCC process. The ME dipole comprises an electric dipole made by two parts of a first metal sheet located on a top substrate layer, a magnetic dipole made by first vias connected to the first metal sheet and a third metal sheet located on a bottom substrate layer, a balun made by an other part of the first metal sheet and a third via, and a reflecting part made by a part of the third metal sheet. The substrate layers are stacked in a multilayer structure to facilitate arranging the metal sheets and the vias.

Abstract: A phase noise suppression method for a multiple-input multiple-output (MIMO) system with a plurality of co-reference channels includes: dividing the phase noise of each channel in the MIMO system into common phase noise and independent phase noise, and constructing a certain number of joint phase states for the independent phase noise; inserting a pilot sequence into the sent signal based on a preset cycle, obtaining the common phase noise based on the pilot at receiver, and performing compensation; and performing signal demodulation on each joint state of the independent phase noise, and comparing the posterior log likelihood values to select the optimal result to output. The above method can significantly improve the phase noise suppression performance of the MIMO system with a plurality of co-reference channels, thereby providing support for improving the system capacity by using MIMO technology.

Abstract: A co-frequency co-time full duplex (CCFD) signal receiving method includes: taking the sent baseband signal as the self-interference reference signal, reconstructing self-interference, and then performing primary self-interference cancellation on the received signal; processing, by using a timing synchronization loop, the signal after the primary self-interference cancellation, realizing timing recovery at the optimal sampling point of the useful signal through resampling a, and controlling resampling b1 and resampling b2 after performing low-pass filtering on the timing error signal in the timing synchronization loop, to recover the optimal sampling points of the self-interference reference signal and the received signal respectively; and performing joint self-interference cancellation and equalization on the resampled self-interference reference signal and the resampled received signal, and receiving the useful signal through signal demodulation. The above method can significantly enhance the self-interference cancellation capability of CCFD technology and improve the receiving performance of the useful signal.
