HiCoMAC: Histogram-State Coded Multiple Access Computing via Computation-Oriented Modulation Design
Xiaojing Yan, Carlo Fischione
Nowadays, over-the-air computation (AirComp) exploits the waveform superposition property of the wireless multiple access channel to directly compute a function of distributed data…
Joint Bit-Partitioning and Modulation Design for Digital AirComp
Xiaojing Yan, Carlo Fischione
For digital over-the-air computation, the ChannelComp framework has recently been proposed to design digital modulations to compute any arbitrary function over a multiple access ch…
Multi-Symbol Digital AirComp via Modulation Design and Power Adaptation
Xiaojing Yan, Saeed Razavikia, Carlo Fischione
Recently, over-the-air computation (AirComp) leverages the superposition property of wireless channels to enable efficient function computation over a multiple access channel (MAC)…
ReMAC:Digital Multiple Access Computing by Repeated Transmission
Xiaojing Yan, Saeed Razavikia, Carlo Fischione
In this paper, we consider the ChannelComp framework, where multiple transmitters aim to compute a function of their values at a common receiver while using digital modulations ove…
A Novel Channel Coding Scheme for Digital Multiple Access Computing
Xiaojing Yan, Saeed Razavikia, Carlo Fischione
In this paper, we consider the ChannelComp framework, which facilitates the computation of desired functions by multiple transmitters over a common receiver using digital modulatio…
