Abstract

The invention discloses a multi-user superposition transmission method, a multi-user superposition transmission device, multi-user superposition transmission equipment and a computer readable storage medium. The method comprises the following steps: carrying out energy transmission maximization processing on modulation symbols of multiple users; superposing the modulation symbols subjected to the energy maximization processing; transmitting signals formed by the superposed symbols through a transmitter, and transmitting energy transmission maximization processing information to all users through control signaling of the transmitter. According to the invention, through carrying out energy transmission maximization processing on modulation symbols of multiple users, mutual cancellation of signals between different users is weakened; while energy transmission is maximized, the transmission performance of the data is ensured; the problem that in the NOMA application process, the sending signal power is reduced due to superposition of multiple user signals is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-user overlay transmission method, device and equipment, and a computer-readable storage medium. Background technique [0002] With the development of technology, wearable devices such as smart glasses and smart watches have emerged in large numbers. In order to avoid frequent charging of such devices, SWIPT (Simultaneously Wireless Information and Power Transfer, wireless information and energy coordinated transmission) has become one of the key technologies to solve the above problems. [0003] At the same time, NOMA (Non-Orthogonal Multiple Access, non-orthogonal multiple access) greatly improves resource utilization and network throughput by performing multi-user data transmission on the same resource. The basic principle of NOMA is: the transmitting side performs multi-user information superposition coding; the receiving side removes the inter-user int...
