Frequency/space diversity data transmission system |
摘要 |
A frequency/space diversity data transmission system includes a transmitter for transmitting two or more distinct RF signals having the same modulation from different antennas separated a wavelength or more, the frequency spacing of the carrier signals being at least ten times greater than the frequency of the modulating signal, and a broad band receiver including a video diode detector and a frequency demodulator which recovers the modulating frequency from the carrier.
