This paper proposes a distributed multiple-access transmission scheme, designed to support the transmission of a small number of active nodes to a central base station when the total number of nodes is large. To achieve this, the authors propose the integration of multiple antenna technologies with compressed sensing algorithms. This integration is made possible by new precoding weight designs which utilize the multiple transmit antennas to provide a power-gain. They demonstrate that the use of these multiple transmit antennas increases the received signal power, thus enhancing the performance of the compressed sensing algorithm.
