Abstract:
1. A method of carrying out a wireless data transmission between first and second units including a base station and a transponder, comprising the following steps: (a) modulating a data packet onto an electromagnetic carrier wave and transmitting said carrier wave with said data packet modulated thereon from said first unit to said second unit, wherein said data packet includes a header section containing a plurality of symbols including a reference symbol and a data encoding symbol, and further includes at least one further section comprising a data section containing encoded data that is encoded by data characters defined with reference to said data encoding symbol; b) receiving said carrier wave with said data packet modulated thereon in said second unit; c) in said second unit, determining a reference time duration of said reference symbol and a time duration of said data encoding symbol in said header section of said data packet; d) in said second unit, adjusting, to an adjusted value dependent on said reference time duration, a parameter that determines at least one property of an encoding and/or decoding process used for encoding and/or decoding encoded data in said second unit; and e) in said second unit, decoding said encoded data using said decoding process having said property thereof determined by said parameter adjusted to said adjusted value; wherein:
