“…The in-band full-duplex (IBFD) technology presents considerable potential to improve spectral efficiency [9], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31]. In this approach, transmission and reception are performed simultaneously using the same frequency resources, which can ideally achieve twice the spectral efficiency of conventional half-duplex (HD) systems [9], [10], [11], [12].…”
