Method and system for blind detection of modulation type |
摘要 |
The invention relates to a method and a receiver for demodulating a modulation symbol in a communication system without knowledge of the modulation constellation employed in a transmitter to modulate this symbol before transmission. According to the method, the invention comprises the steps of interpreting the modulation symbol as a symbol of one of a family of hierarchical modulation constellations, decoding the demodulated symbol using a forward error correction (FEC) technique and demodulating the symbol according to the assumed modulation constellation. Finally, the demodulated symbol is checked for correctness. The receiver comprises of a corresponding interpretation unit, a demodulator and an FEC decoder as well as means for checking the correctness of the demodulated symbol.
