  • Selection between two different coding schemes and corresponding modulation schemes according to the allowable transmission delay of the data
    Patent number: 7339911
    Abstract: Transmitters comprising detectors (32) for detecting packet data to be transmitted are provided with selectors (34) for in response to detection results of real-time requirements selecting first coding schemes and first modulation schemes like convolutional codes and adaptive orthogonal frequency division modulation schemes and for in response to non-real-time requirements selecting second coding schemes and second modulation schemes like turbo codes and orthogonal frequency division modulation schemes, to transmit with increased efficiency. Further detection results comprise target bit error rates and/or a payload bit rates, and further detectors (33) detect channel conditions. A processor system (20) runs adaptive algorithms for evaluating a maximum available bit rate in dependence of said channel conditions and/or margin adaptive algorithms for computing a bit loading in dependence of an actual bit rate.
