Abstract
Cyclic prefix (CP) detection and removal in a wireless communications system (WCS) is disclosed. More specifically, embodiments disclosed herein relate to removing a CP(s) from a random-access symbol(s) in an open radio access network (O-RAN) communications system in the WCS. The random-access symbol(s) includes the CP followed by a random-access sequence. As such, the CP must be removed before the random-access sequence can be detected and processed. In this regard, in embodiments disclosed herein, the O-RAN communications system is configured to determine a group delay associated with the random-access symbol(s) to thereby accurately determine a start of the CP in the random-access symbol(s). Accordingly, the O-RAN communications system can detect and remove the CP from the random-access symbol(s) based on the determined start of the CP. As a result, it is possible to preserve integrity of the random-access symbol(s) to thereby reduce random-access latency in the WCS.
