Proportional Fair Scheduling

The interferences of radar and communication system coexistent environment are analyzed in this paper, and an attractive detection mechanism of the radar video signal and proportional fair scheduling algorithm based on channel sensing are proposed to realize the communication by using radar radiant intermissions. And the simulation is designed based on the proposed model to test this plan. The simulated results show that the packet scheduling algorithm is an excellent candidate for the communication solution for LTE system under radar radiant intermissions.

Packet Scheduling Algorithm

This paper puts forward a new dynamic round-robin (DYRR) packet scheduling algorithm with high efficiency and good fairness. DYRR algorithm introduces dynamic round-robin concept, that is, the allowance given to each of the flows in a given round is not fixed, but is related with the number of bytes sent of this and other flows of the last round scheduling. The time complexity of the DYRR algorithm is O(1). Results from performance simulation analysis shows that DYRR algorithm can effectively smooth output burst, realize fair scheduling, and have a good time delay characteristic.
