Periodic Ambiguity Function as a Tool in Designing Periodic Synchronization Preamble
The paper introduces the periodic ambiguity function (PAF) of the preamble code as a tool in designing periodic synchronization preamble. It is shown that in the considered low-complexity receiver architecture characteristics of the PAF, namely, sidelobes peak level and main lobe phase, play an important role in the quality of the channel estimation. Furthermore, it is shown that these PAF characteristics vary considerably with the circular shift of the preamble code and care should be taken when selecting both preamble codes and corresponding circular shifts. This is done on an example of the preamble design for high pulse repetition frequency (HPRF) mode of the upcoming IEEE 802.15.4z standard amendment for enhanced ultra wideband (UWB) physical layers (PHYs) and associated ranging techniques. Similar analysis is carried-out on the preamble codes already specified in the high-rate pulse repetition frequency (HRP) UWB PHY of the IEEE 802.15.4-2015 standard.
