摘要

A technology that allows wireless signals to be sent and received simultaneously on a single channel, with no 'time division multiplexing' whatsoever has now just been developed by Stanford, USA, researchers. In the past, full-duplex communications, i.e. for simultaneous transmit and receive, required either two frequencies, one for transmit and another for receive, or a very fast 'ping-pong' transmit/receive cycle combined with digital encoding to give near-instantaneous transmit and receive on a single channel although this naturally at least halved the amount of 'throughput' in terms of bandwidth that could be used on a given channel.
