[en] This paper studies the concept of jointly utilizing the data information
(DI)
and channel state information (CSI) in order to design symbol-level precoders for a multiple input and single output (MISO)
downlink channel. In this direction, the interference among the simultaneous data streams
is transformed to useful signal that can improve the signal to interference
noise ratio (SINR) of the downlink transmissions. We propose a maximum ratio
transmissions (MRT) based algorithm that jointly exploits DI and CSI to gain the benefits from these useful signals. In this context, a novel framework to minimize the power consumption
is proposed by formalizing
the duality between
the constructive interference downlink channel and the multicast channels. The numerical results have
shown that the proposed schemes outperform other state of the art techniques.
