Abstract: A method (700) includes receiving (701) a receive signal (x[n]) comprising a periodic data signal component (r[n]) and a periodic interference signal component (s[n]); determining (702) an average value by averaging over sub-samples of the receive signal (x[n]), wherein the average value is independent of at least one sub-sample of the receive signal (x[n]) having a same phase as a particular sample ([n]) of the receive signal (x[n]); and determining (703) for the particular sample ([n]) of the receive signal (x[n]) an estimate (?[n]) of the interference signal component (s[n]) based on the average value.

Abstract: This disclosure describes enhanced directional multi gigabit (EDMG) physical layer convergence procedure (PLCP) protocol data unit (PPDU) frames and frame formats for wireless networks. The frame can include a legacy portion and a non-legacy portion. The legacy portion of the frame can be transmitted using a legacy sample (or chip) rate. The non-legacy portion of the frame can be transmitted using a second, different sample (or chip) rate. A transition interval field may be defined between the legacy and the non-legacy portions of the frame, the transition interval field having a predetermined time duration. In one embodiment, the transition interval field can be defined and/or used in connection with one or more standards (for example, a IEEE 802.11ay standard). The various embodiments disclosed herein can be used to facilitate hardware implementation, increase vendor-agnostic compatibility, and allow for accurate, vendor agnostic time-of-flight (ToF) measurements.
