Symbiotic radio (SR) backscatter is a possible low-power wireless communication technique for future Internet of Things devices. In this letter, multiple-input-multiple-output (MIMO) SR system proposed, where the secondary multi-antenna transmission from device (BD) to receiver riding on primary transmitter receiver. We investigate beamforming design optimization problem which maximizes sum cap...

The paper proposes mvTANTs , three-level networks with multiple-valued inputs and binary outputs. These networks are a generalization of binary T A N T s (Three level And Not networks with True Inputs). One of possible interpretations of m v T A N T is a four-level binary network with input decoders which realize multiplevalued literals. Similarly to mvPLAs, mvTANTs have regular structures with...

We describe a new class of translinear circuits that accurately embody product-of-power-law relationships in the current signal domain. We call such circuits multiple-input translinear element (MITE) networks. A MITE is a circuit element, which we defined recently, that produces an output current that is exponential in a weighted sum of its input voltages. We describe intuitively the basic oper...
