AN ADAPTIVE SELF-INTERFERENCE CANCELLING SYSTEM FOR 5G FULL DUPLEX AND MASSIVE MIMO SYSTEMS

摘要

A full-duplex self-interference cancelling system operable in 28 GHz data rate levels, therefore well compatible with 5G systems such as massive MIMO transmitter-receiver radios and mm-waves, designed to include an antenna to improve signal-to-noise ratios (SNR) and elimination of self-interference-based noise and an adaptive, blind performing self-interference canceller module. In other words, the present invention comprises a self-interference canceller using variable-gin amplifiers to adjust a receiving signal post-dissection into in-phase and quadrant constituents thereof via an I/Q modulator, entire process of which is overseen and dictated by a digital control block.
