Abstract :
The advanced single-channel antijam man-portable (ASCAMP) downlink is a custom-designed digital signal processor implemented in hardware that runs a tailored and efficient microcode. Appropriate sections of microcode are executed in response to the downlink requirements. The different processing functions, hardware design, and hardware implementation are discussed. The author points out the unique feature of reprogramming field programmable gate array (FPGA) hardware in order to accomplish different processing tasks with minimal hardware. Advantages and disadvantages of using FPGAs in the advanced SCAMP implementation and ideas for future development are mentioned. The ASCAMP (EHF satellite communication terminal) has stringent size, power, and weight specifications, making for a challenging design project. The downlink processor implementation has been optimized both in concept and design to meet these specifications
