摘要
Orthogonal Frequency-Division Multiplexing(OFDM)is the form of a digital system and a way of encoding digital data across multiple frequency com-ponents that are used in telecommunication services.Carrier Frequency Offset(CFO)inaccuracy is a major disadvantage of OFDM.This paper proposed a fea-sible and elegant fuzzy-based resource allocation technique,that overcomes the constraints of the CFO.The suggested Fuzzy linear CFO estimation(FL-CFO)not only estimates the CFO with increased precision but also allocates resources effectively,and achieves maximum utilization of dynamic resources.The sug-gested FL-CFO error estimation algorithm in OFDM systems employing 1-bit Quadrate errors ADC(1-bit QE)is utilized to extract the precise CFO.Addition-ally,the base station(BS)manages the Resource Units(RU),which could be used to distribute resources in such a manner that the user requests are met.To assign resources to a certain job,fuzzy rules are devised.When the residence duration exceeds the resource requirement time then the particular resources are provided to the highest-priority jobs.As a result,the job performance will not be halted due to a lack of allocated resources.Performance metrics such as utilization,rate of failure,and life span,as well as energy consumption,are used to assess the pro-posed FL-CFO.
