Superimposed signaling inspired channel estimation in full-duplex systems

Koohian, Abbas; Mehrpouyan, Hani; Nasir, Ali A.; Blostein, Steven D.; Durrani, Salman

Description

Residual self-interference (SI) cancellation in the digital baseband is an important problem in full-duplex (FD) communication systems. In this paper, we propose a new technique for estimating the SI and communication channels in a FD communication system, which is inspired from superimposed signaling. In our proposed technique, we add a constant real number to each constellation point of a conventional modulation constellation to yield asymmetric shifted modulation constellations with...[Show more]
