Array Signal Processing for Communications from High Altitude Platforms and Other Applications
… the communications from high altitude platforms (HAPs) and the high data rate OFDM signal transmission in underwater acoustic channel are respectively investigated. Both conventional and adaptive beamforming methods are investigated in the application to HAP communications. A three-step footprint …
