WCDMA payloads on fast-moving platforms, such as on satellites in Molniya orbits or on UAVs, will likely be added to the battlefield to assure the warfighter of reliable, ubiquitous communications. The algorithms for handoffs, timing, and Doppler correction suitable for near-Geosynchronous platforms will not be suitable for these fast movers. Power control algorithms may or may not be suitable. This project determines the necessary modifications to commercial and military WCDMA algorithms to support intra and inter platform handoffs, timing synchronization, power control, and Doppler correction.
