Abstract
A wireless transmission system and method for supporting the full-duplex transmission of baseband data within a single RF band, is presented herein. The system includes a modem that modulates the baseband data with a spectrally efficient modulation technique. The system also includes a transceiver that accommodates the wireless transmission of data within a first sub-band of frequencies derived from the single RF band and the wireless reception of data within a second sub-band of frequencies derived from the single RF band. The system further includes combline band-pass filters and a dual orthogonal feed antenna to ensure the isolation and separation between the first and second sub-bands.
Claims22
A wireless transmission system for supporting the full-duplex transmission of data within a single frequency range, said wireless transmission system comprising:
- a modem configured to modulate baseband data to generate modulated baseband data signals and to demodulate modulated baseband data signals into baseband data;
- a transmit mechanism operatively coupled to said modem and configured to convert the modulated baseband data signals into transmit radio-frequency signals, wherein the transmit radio-frequency signals operate within a first sub-band of frequencies derived from the single frequency range and contain a carrier frequency centered in said first sub-band of frequencies;
- a transmit radio-frequency band-pass filter operatively coupled to said transmit mechanism and configured to filter the transmit radio-frequency signals within said first sub-band of frequencies, said transmit radio-frequency band-pass filter comprising a narrowband filter having response characteristics that substantially reject signals outside said first sub-band of frequencies;
- an antenna mechanism operatively coupled to said transmit radio-frequency band-pass filter and configured to radiate the transmit radio-frequency signals and to collect receive radio-frequency signals;
- a receive mechanism coupled to said modem and configured to convert the receive radio-frequency signals into modulated baseband data signals, wherein the receive radio-frequency signals operate within a second sub-band of frequencies derived from the single frequency range and contain a carrier frequency centered in said second sub-band of frequencies;
- and
- a receive radio-frequency band-pass filter operatively coupled to said receive mechanism and said antenna mechanism and configured to filter the receive radio-frequency signals within said second sub-band of frequencies, said receive radio-frequency band-pass filter comprising a narrowband filter having response characteristics that substantially reject signals outside said second sub-band of frequencies.
