Abstract: PURPOSE: A detector detecting the energy in the band of frequency and a distortion correcting circuit are provided to reduce the detected energy in the band of detected frequency by responding to the detector at a certain offset from the central frequency of the signals of a base band. CONSTITUTION: An amplifying system(100) is composed of an amplifier(102), a control system(104), and a pre-distorter(105). Herein, the amplifying system amplifies input signals inputted via a line(101) and provides amplified output signals to a line(103). The amplifier is biased A/B grades and represents a non-linear amplifying characteristic. Thereby the non-linear amplification by the amplifier causes the amplitude distortion and the phase distortion to the amplified output signals. If the signals pass through the amplifier, the elements of frequency out of bandwidth are generated. Herein, the output signals generated by the amplifier are supplied to the pre-distorter by using the control system. The pre-distorter receives the input signals on the line(101) and the output of the control system via adjustable lines(109). The pre-distorter has a ratio of the non-linear gain to the level of the input signals selected according to the out-of-band feedback control signals. Thereby, the amplifying system supplies the ratio of the output power of the amplifier to the power transmission of the input signal, which is substantially linear for the input signals.

Abstract: A dictionary based data compression and decompression system where, in the compressor, when a partial string W and a character C are matched in the dictionary, a new string is entered into the dictionary with C as an extension character on the string PW where P is the string corresponding to the last output compressed code signal. An update string is entered into the compression dictionary for each input character that is read and matched. The updating is immediate and interleaved with the character-by-character matching of the current string. The update process continues until the longest match is found in the dictionary. The code of the longest matched string is output in a string matching cycle. If a single character or multi-character string "A" exists in the dictionary, the string AAA . . . A is encoded in two compressed code signals regardless of the string length. This encoding results in an unrecognized code signal at the decompressor. The decompressor, in response to an unrecognized code signal, enters update strings into the decompressor dictionary in accordance with the recovered string corresponding to the previously received code signal, the unrecognized code signal, the extant code of the decompressor and the number of characters in the previously recovered string.
