  • Arrangement for the optimization of the data transmission via a bi-directional radio channel
    Patent number: 6262994
    Abstract: The arrangement is for optimization of data transmission via a bi-directional radio channel in which respective types of modulation can be selected at the transmitter side and the code rate of the forward error correction (FEC) as well as the power of the transmitter Devices (CRC) are provided at the reception side for determination of the error rate. The size of the data packets, and/or the type of modulation, and/or the code rate, and/or the power of the transmitter is varied, dependent on the error rate transmitted back, such that a predetermined error rate is achieved at the reception side.
