1. An apparatus for setting a transmission-rate parameter for transmission of information units in a wireless communication system, comprising:

  • a total counter for counting a total number of received information units in a single received sequence of L-slot Pulse Position Modulation (L-PPM) information units;

    an error counter for counting an error number of invalid received information units in the sequence of L-PPM information units;

    a division unit for dividing said error number by said total number, the division result being providable as a link-quality measure at an output of said division unit, characterized in that said division unit is adapted to automatically perform binary divisions by 2 using a shift operation after n information units are received, where n is some integral power of 2; and

    a decision unit for setting said transmission-rate parameter by comparing said link-quality measure with at least one predefined value and defining said transmission-rate parameter to assume a corresponding data rate.
