Multi-Modulator for Bandwidth-Efficient Communication
Read More >>
Coding and modulation can be selected by loading configuration bits into an FPGA.
A modulator circuit board has recently been developed to be used in conjunction with a vector modulator to generate any of a large number of modulations for bandwidth-efficient radio transmission of digital data signals at ...Read More >>
Microwave Power Combiners for Signals of Arbitrary Amplitude
Read More >>
Output polarization would no longer vary with input amplitudes.
Schemes for combining power from coherent microwave sources of arbitrary (unequal or equal) amplitude have been proposed. Most prior microwave-power-combining schemes are limited to sources of equal amplitude.Read More >>
Airborne Antenna System for Minimum-Cycle-Slip GPS Reception
Read More >>
The antenna is kept pointing upward as the airplane banks.
A system that includes a Global Positioning System (GPS) antenna and associated apparatus for keeping the antenna aimed upward has been developed for use aboard a remote-sensing-survey airplane. The purpose served by the system is to enable minimum-cycle-slip ...Read More >>
