The proliferation of smartphones, tablet PCs and laptops is continually boosting demand for higher throughput of mobile devices with advanced wireless network capabilities. Between 2014 and 2019, global mobile data traffic is expected to increase nearly tenfold – expanding at a rate of 57% each year . To support such demand, fifth generation (5G) wireless communications are expected to provide 1000-fold greater throughput than 4G. The wireless spectrum used to carry this traffic, however, is physically limited. This fact could give rise to a spectrum crunch. To increase spectral efficiency, researchers have developed several promising technologies. One of them, which could potentially double spectral efficiency, is known as full duplex.
Full-duplex radios simultaneously transmit and receive in the same frequency band. ...
