Multi-modulation scheme compatible radio |
| 摘要 |
A transceiver compatible with both wide channel constant envelope 4 level FSK FM modulation and narrow channel pi /4 differential QPSK linear modulation allows compatible interaction between modified constant envelope and non-constant envelope transmitters. All Nyquist filtering occurs in the transmitters, and none in the receiver.
