System and method for communicating data using constant envelope orthogonal walsh modulation with channelization |
摘要 |
<p>A radio device includes a transmitter having a modulator for generating M-PAM communications symbols containing communications data. A Fast Walsh Transform circuit orthogonally encodes and band-spreads a communications symbol using the Fast Walsh Transform. A frequency modulation circuit frequency modulates the communications symbols wherein a constant envelope orthogonal Walsh modulated communications signal is generated having a plurality of orthogonal waveforms each forming a separate Walsh communications channel.</p> |
