| 摘要 |
A method for demodulating a signal modulated with a first phase modulation technique with a demodulator adapted to demodulate signals modulated with a second phase modulation technique, the first phase modulation technique being based on a first phase constellation diagram and the second phase modulation technique being based on a second phase constellation diagram, the second phase constellation diagram being obtained by rotating the first phase constellation diagram by an angle being a non-nul integer multiple of 90 degrees, the method comprising:
a) rotating the signal modulated with the first phase modulation technique by said angle; and
b) demodulating the rotated signal with the demodulator. The method enables to use former optimized demodulator. |
