System Resource Allocation and Rural Industry Revitalization Based on Max-Min Algorithm

Table 2

Advantages and disadvantages of OFDMA system subcarrier allocation algorithm.

Algorithm name	Advantage	Disadvantage
Maximum carrier-to-interference ratio algorithm	Best single user, maximum throughput	The only goal is to maximize the total system throughput, which does not meet the fairness criterion
Minimal capacity user maximization algorithm	Ensure the fairness of throughput between users, and the algorithm complexity is low	Does not consider the QoS requirements of different business users
Proportional fairness algorithm	Different trade-offs can be made between throughput and fairness	In the case of multiple services, the number of remaining subcarriers is greater than the number of users
