Definitions

  • a wireless microphone and / or in-ear monitoring system is provided with at least a first mobile device, in particular a wireless microphone for wireless transmission of first audio signals.
  • the system further comprises at least one base station for wirelessly receiving first audio signals transmitted by the at least one mobile device.
  • the wireless transmission is based on a Orthogonal Frequency Division Multiplexing (OFDM) transmission during a Time Division Multiple Access TDMA time slot.
  • OFDM Orthogonal Frequency Division Multiplexing
  • Each wireless microphone occupies at least one time slot within 2ms.
  • Each of the TDMA frames has a plurality of slots each having exactly one OFDM symbol. This transfers exactly one OFDM symbol in each TDMA slot.
  • a transmission is made based on an OFDM method.
  • the TDMA frame length is so short, as a latency of ⁇ 4ms is needed for a professional audio transmission eg in wireless microphone systems.
  • FIG. 2 shows a schematic frame structure of a wireless transmission according to the first embodiment
  • FIG. 3 shows a schematic representation of a synchronization process in the case of the wireless transmission according to the first exemplary embodiment.
  • the wireless microphone and / or in-ear monitoring system according to the invention represents a so-called Program Making Special Event System PMSE.
  • a measurement of the carrier frequency offset (CFO) in the base station may be superfluous.
  • the mobile device MT is designed such that no data is sent to the base station BS until a time synchronization takes place. has found.
  • an extended cyclic extension CP By means of an extended cyclic extension CP, remaining inaccuracies with regard to the time synchronization and the transit time differences can be compensated.
  • the base station does not have to perform time synchronization.
  • the mobile device MT corrects the carrier frequency offset (CFO) and sets the receive FFT window. Before the mobile device MT transmits the data in the microphone slots M, the carrier frequency is shifted by the measured carrier offset (CFO) and a time period for the transmit FFT window is determined.
  • the base station BS receives the payload data in the microphone slots M without having to perform a frequency or time synchronization.
