Abstract: A system is presented for utilizing data in a mobile device in real-time and without the need for additional hardware. The system allows real-time processing of highly-compressed data that would otherwise require processing power in excess of that available from the system, or would otherwise not be possible without additional hardware. The system generally includes a processing device that receives the data in a highly compressed format, and includes a preprocessor that pre-processes the data to at least partially decode the data into a second compressed format. The processing device also includes a decompressor that fully decompresses the preprocessed data as needed by the system. The processing device may also include one or more memories for storing the preprocessed data until it is needed by the system.

Abstract: Controlling a cellular radio frequency repeater amplifier and their gain factors. In preferred embodiments, the method is used in personal home repeaters that may be used by wireless services users. The repeaters are preferably configured to automatically control their setting without requiring supervision or control by the wireless service provider.

The preferred system and methods reduce potential problems that may arise when repeaters with fixed gain are placed within close proximity of a cell site. The preferred methods shut down the forward and reverse amplifiers based on the received signal level from the base station.

Abstract: The emittance value is a measure of an amount of energy expelled from a given surface area relative to a black-body reference. Depending on the specific coating a change in the emittance value is actively or passively effected. There are known active variable emittance thermal control coatings. However, such coatings are actually panels housing a mixture of both high and low emissivity materials that are electrically manipulated to control the emittance value of the panel. These “coatings” are classified as either electrochromic or electrophorectic. Both electrochromic and electrophorectic coatings require an applied voltage to cause a change in the emittance value of the coating. By contrast, aspects of the present invention do not include active variable emittance thermal control coatings. Aspects of the present invention do include passive variable emittance thermal control coatings and materials.

The user's mobile terminal receives the received data from the first mobile terminal having the good reception state by a wireless communication method.

Abstract: A novel and useful apparatus for and method of local oscillator (LO) generation with non-integer multiplication ratio between the local oscillator and RF frequencies. The LO generation schemes presented are operative to generate I and Q square waves at a designated frequency while avoiding the well known issue of harmonic pulling. The input signal is fed to a synthesizer timed to a rational multiplier of the RF frequency L/N fRF. The clock signal generated is divided by a factor Q to form 2Q phases of the clock at a frequency of L(N*Q)fRF, wherein each phase undergoes division by L. The phase signals are input to a pulse generator which outputs a plurality of pulses. The pulses are input to a selector which selects which signal to output at any point in time. By controlling the selector, the output clock is generated as a TDM based signal. Any spurs are removed by an optional filter.

An RF power amplifier that exhibits a high power-added efficiency characteristic regardless of whether the output power is High or Low can be materialized.

Abstract: Disclosed is a channel estimator and a method for changing a coefficient of an IIR filter depending on a moving speed of a mobile communication terminal. In the channel estimator, a coefficient changing unit receives I and Q signals from a current base station, and selects a coefficient of the IIR filter optimized depending on the moving speed of the current mobile communication terminal. The coefficient changing unit sets the selected coefficient of the IIR filter to the IIR filter of the channel estimator. Accordingly, it is possible to prevent the performance degradation of the channel estimator caused by the speed of the mobile communication terminal.
