Abstract: Systems, methods, and apparatuses are provided for linear envelope elimination and restoration transmitters that are based on the polar modulation operating in conjunction with the orthogonal recursive predistortion technique. The polar modulation technique enhances the battery life by dynamically adjusting the bias level. Further, the analog orthogonal recursive predistortion efficiently corrects amplitude and phase errors in radio frequency (RF) power amplifiers (PA) and enhances the PA output capability. Additionally, even-order distortion components are used to predistort the input signal in a multiplicative manner so that the effective correction bandwidth is greatly enhanced. Also, the predistortion scheme, which uses instantaneously feed-backed envelope distortion signals, allows for correction of any distortion that may occur within the correction loop bandwidth, including envelope memory effects.

Abstract: A method of backing up and recovering data in a data processing system is disclosed. The method includes selecting files to be backed up, and determining where to save selected files; loading a project file to manage backup information on the selected file; building a baseline in the project file; backing up the selected files with the baseline, and updating a backup file DB including information on storage addresses where the selected files are saved; and completing data backup by saving an updated backup file database (DB) in the project file. With this configuration, the present invention provides a method for backing up and recovering data by using a baseline, in which a baseline is built in a project file whenever data backup is performed, so that not only is the data easily backed-up and recovered even if the data backup is repeatedly performed and an amount of data is managed, but also a space of a storage unit that is used to store the backup files is efficiently used.
