DIGITAL MODULATION METHOD AND APPARATUS, AND METHOD AND APPARATUS FOR PROVIDING MULTIPLE SERVICES USING SAID DIGITAL MODULATION |
| 摘要 |
The present invention discloses a digital modulation method for providing multiple services. The method for providing multiple services comprises multiplexing bits by allocating them according to a required SNR (Signal to Noise Ratio) of each service; and modulating multiplexed bits by applying non-uniform distances among constellation symbols. |
