Abstract

The invention belongs to the technical field of communication, and particularly relates to a power distribution method based on imperfect serial interference elimination. The method comprises the steps that a base station sets a unit power price and sends the set price to a user side; the user side determines the amount of power purchased from the base station according to the price set by the base station, and sends the amount of power purchased to the base station; the base station readjusts the update price according to the power purchase amount of the user side; the base station and the user continuously play a game until the power price of the base station and the power purchase amount of the user reach a balanced state; and the equalized user power is obtained, and power distributionis completed. According to the invention, the power distribution method based on imperfect serial interference elimination is adopted on the premise of ensuring the service quality and the user fairness, so that the algorithm is simpler and more accurate.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a power allocation method based on imperfect serial interference elimination. Background technique [0002] With the development of mobile communication technology, it has expanded from pure voice service to mobile Internet service. Mobile traffic is growing exponentially due to the rapid development of the Internet of Things. The traditional orthogonal multiple access has limited spectrum efficiency and allowed access users, which cannot meet the explosive user growth. Different from the orthogonal multiple access method, the non-orthogonal multiple access can overlap and multiplex multiple users in the same frequency band, and eliminate the interference caused by other users through the Serial Interference Cancellation (Successive Interference Cancellation, SIC) technology. As one of the key technologies of 5G (5th-Generation), Non-Orthogonal Multiple Access...
