A positioning system () for determining location information of/for a mobile radio transmitter () comprises an antenna system () which includes a plurality of antennas () aimed at different directions and arranged on one common antenna carrier (). The positioning system () comprises a receiver system () electrically connected to the antennas () and configured to receive via each of the antennas () a radio signal () transmitted by the mobile radio transmitter (). The positioning system () further comprises a processing circuit () electrically connected to the receiver system () and configured to calculate the location information of/for the mobile radio transmitter () based on the radio signal received at each of the antennas (). The location information includes at least angular direction of the mobile radio transmitter () with respect to the antenna system ().

System and method for determining location information for a mobile radio transmitter

An RFID receiver () comprises an antenna () configured to receive a radio signal () from an RFID transmitter () and to generate an electrical signal () from the radio signal () received from the RFID transmitter (). A decoder circuit () is connected to the antenna () and configured to extract from the electrical signal () generated by the antenna () data bits encoded in the electrical signal (). The decoder circuit () comprises an analog-to-digital converter () connected directly to the antenna () and configured to generate a digital input signal () from the electrical signal () generated by the antenna (). A bit extractor () is connected to the analog-to-digital converter () and configured to extract the data bits from the digital input () signal generated by the analog-to-digital converter ().
