Polar codes have been applied for physical downlink control channel in the 5th generation wireless communication system. Although successive cancellation flip (SCF) decoding algorithm can improve decoding performance of polar codes. it has also led to the increasing in decoding latency and calculation complexity. Candidate flipping positions set (CFPS) of traditional SCF decoding is c... https://www.spidertattooz.com/USC-Trojans-9FIFTY-Snapback-Hat/
