DIGITAL DEMODULATION METHOD AND SYSTEM |
| 摘要 |
A digital demodulation system calculates an I channel value and a Q channel value of a received signal. The digital demodulation system then changes detection levels to obtain non-uniform detection levels. The digital demodulation system then demodulates the received signal bit by bit by using the changed detection levels and the I channel value and the Q channel value. |

1. A digital demodulation method for a digital demodulation system that demodulates a received signal, the method comprising:
calculating an I channel value and a Q channel value of a received signal; changing detection levels to obtain non-uniform detection levels; and demodulating the received signal bit by bit by using the changed detection levels, the I channel value, and the Q channel value. |
