Research on Resource Allocation Algorithm Based on OFDM Communication System

Wireless communication relies on resource allocation to realize data transmission. The complex communication environment challenges resource allocation under harsh conditions, so optimizing resource allocation in communication system is very important. This paper explores the resource allocation problem of communication system, and designs and implements a low complexity resource allocation algorithm based on OFDM communication system. Three normalized resource allocation processing methods are used to optimize the resource allocation of water injection algorithm, so as to reduce the computational complexity and running time of the system and improve the capacity performance of the system. The results show that the strategy has a significant effect on improving the performance of OFDM communication system, and can effectively deal with the problems of low delay and transmission efficiency in the communication system, and achieve and optimize the resource allocation goal.
