doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> January 2014 Motivation: For sync performance evaluation in AWGN a lot of additional parameters exists These parameters have a significant influence on the sync performance Example: False Acquisition Rate (FAR) @ 3dB Es/N0 with different parameters: Agreement on a common set of parameters is desirable 0.001 0.11 0.43 Frederik Beer, Jörg Robert <author>, <company>

Two possible approaches to find start of packet: January 2014 Simulation Model: Two possible approaches to find start of packet: Correlate at all possible positions in the search area and pick the maximum Subsequently correlate with starting at the beginning and stop whenever result exceeds a defined threshold Frederik Beer, Jörg Robert

January 2014 Simulation Model: Exemplary set of parameters to make results comparable: Search area: 2048 samples Oversampling factor: 8 Max. frequency offset: ±43.4 kHz (50 ppm @ 868 MHz) Datarate: 100 kbps Uniformly random placement of packet Packet consists of: Preamble + SFD + 20 octet random data Sweep parameter N0 Results shall be plotted over an ES/N0 Length and bitmapping of preamble and SFD are subject to the proposals Used synchronisation algorithm does not have to be disclosed Frederik Beer, Jörg Robert
