New millimeter-wave transceiver doubles spectrum efficiency, eliminates self-interference (opens in new tab)

A newly developed architecture for full-duplex wireless transceivers solves the long-standing problem of self-interference, as reported by researchers from Science Tokyo. They implemented an innovative switching strategy that isolates self-interference in the time domain by alternating transmission and reception faster than the wireless signal period, enabling effective simultaneous transmission and reception. Experiments using 400-MHz-wide millimeter-wave signals (5G-compatible) highlight th...
