Bandwidth-Efficient Modulation
نویسندگان
چکیده
The recent proliferation of terrestrial and space-based communication systems has given rise to an increasingly critical problem—the lack of available frequency spectrum. One tool that satellite system designers can use to maximize the use of available spectrum is bandwidth-efficient modulation. This technique can enhance bandwidth efficiency while retaining reasonable power efficiency and implementation complexity. Because of the wide applicability of bandwidth-efficient modulation to most new satellite systems, The Aerospace Corporation has performed extensive research in this area. One recent application can be found in the Advanced Extremely High Frequency (AEHF) program.

متن کاملImproved bandwidth in VCSEL with AC Modulated Holding Beam
A modulated holding beam shining a VCSEL above threshold can improve modulation bandwidth by adjusting the semiconductor laser’s relaxation oscillation frequency. The improved modulation characteristics are accompanied by reduced damping rate. By choosing correct parameters, dynamical behavior of system and cavity solitons is changed.
