ABSTRACT:
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 the communications symbols using the Fast Walsh Transform. A frequency modulation circuit frequency modulates the communications symbols wherein a constant radius orthogonal Walsh modulated communications signal containing the communications data is generated.
