[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] A power domain non-orthogonal multiple access decoding method, the implementation steps are as follows:
[0022] Step 1. The base station performs channel coding (such as low-density parity check code, Turbo code, polar code, etc.) and modulation on the signals sent to user 1 and user 2, respectively, to obtain transmission information symbols. and . The base station determines the transmit power allocated to user 1 and user 2 and . The base station uses superposition modulation to transmit signals to user1 and user2.
[0023] Step 2. User 1 receives a signal . Among them, the path gain from the base station to user 1 is h 1 , represents the noise power as background white Gaussian noise. User 1 first decodes user 2 information symbols , in the traditional method, the signal of user 1 is treated as Gaussian white noise at th...
