SyncCorr (MB-OFDM)
Menu Path:
Sync Corr (Synchronization Correlation) is the correlation between the measured Packet/Frame Synchronization section of the preamble and an ideal Packet/Frame Synchronization. It represents an indication of the quality of the Packet/Frame Sync section in the preamble. For MB-OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS., this is a linear correlation expressed in percentage as specified in the standard. (See About Opt BHB: Multiband-OFDM.) A value of 100% indicates perfect correlation and a value of 0 indicates no correlation.
Sync Correlation is a symbol by symbol correlation of the Packet/Frame Sync section in the preamble, PS physical slot: A unit of time, dependent on the PHY specification, for allocating bandwidth. 802.11: Power save (mode)/FS fixed subscriber: A subscriber station that does not support communications whilst in motion. (Sync), with the individual parts RMS averaged to compute the final result as specified in the standard.
"SYNC NOT FOUND" on a trace is triggered by Sync Corr being unacceptably low. See Trace Problems for more information on diagnosing this problem.
