Abstract
The present application relates to a method for embedded data modulation over pilot symbols in a QAM system. Based on the concept of embedding data modulation, the CPE pilot symbols are also used to carry data, which is modulated in amplitude or in both amplitude and phase. Thus, it is proposed a better use of the necessary CPE-pilots overhead to enhance the Information rate of a transmitted signal. Based on the concept of embedding data modulation over CPE pilot symbols, it is also object of the present disclosure a method for transmitting embedded data modulation over pilot symbols in a QAM system and a method for receiving embedded data modulation over pilot symbols in a QAM system.
