WIRELESS COMMUNICATION RESOURCE ALLOCATION METHOD AND SYSTEM BASED ON ENERGY EFFICIENCY

摘要

Disclosed are a wireless communication resource allocation method and system based on energy efficiency, and said method comprises the following steps: classifying each source node based on the channel condition information of each source node in a source node set to be allocated to a destination node; allocating a subcarrier of the best channel quality to said each source node based on said classification; judging whether all the source nodes reach a destination data rate; respectively judging whether energy efficiency of each said source node selected is improved; judging whether source nodes to be allocated do not exist in said source node set to be allocated, or whether all the subcarriers are occupied, if so, then finishing the resource allocation process, if not, returning to the step of judging whether all the source nodes reach the destination data rate. In the invention, since system energy efficiency is maximized by allocating subcarriers, power and bits jointly, complexity of realizing the resource allocation process is lowered greatly, and reliability of the system is improved effectively.
