摘要: In this paper, we present practical realization of spectrum sharing scheme for machine-type communications in LTE. We demonstrate that the proposed supports dynamic access large set low-data rate transmitters. Unlike classical random-access type communications, new avoids need signaling procedures are associated with channel reservation. Moreover, compressive-sensing based algorithm is able to identify transmitting nodes and simultaneously decode multi-user data. The has been implemented on software-defined radio TD-LTE testbed.
