Full duplex voice communication handsets over single carrier frequency
K.S. Subramanyam, A.K. Gogoi · 2002
A new technique for realization of two-way voice communication over a single carrier frequency as an improvement over the usual walky-talky type, simplex handsets, which are very widely used for civil as well as for military applications, is proposed. The challenge lies in providing cost-effective, full-duplex digital voice communication handsets, conserving the bandwidth at the same time.
