    Abstract: PROBLEM TO BE SOLVED: To increase radio resistance to radio frequency interference from another system while moving to the neighborhood of the antenna of a difference system concerning mobile radio. SOLUTION: When the power level of a received signal satisfies or exceeds a prescribed power threshold as the result of detecting the level, a low noise amplifier is by passed to improve the intercept point the component of a receiver. An alternative solving means controls a front end gain continuously as the function of interfering power by using an RF power detector to suppress interference and to adjust the sensitivity of the receiver by a signal level lower than a switchable gain block. Adjusting input gain by each prescribed quantity, the processor of the receiver measures the variation of the gain of an IF signal power. When the variation is smaller than a prescribed quantity, since a CDMA signal and the interfering power is lower than the noise lowest value, the gain is increased. When the variation of the IF signal is larger than the prescribed quantity, the gain is reduced to reduce a mutual modulation product. It is continued until the receiver operates at the best compromise of interference and a noise index.

    Abstract: PROBLEM TO BE SOLVED: To provide local oscillator leakage control in direct conversion processes. SOLUTION: A system and method for generating a local oscillator (LO) frequency in a zero intermediate frequency (IF) receiver or transmitter is presented. A signal is received from a voltage controlled oscillator (VCO). The signal has a VCO frequency. The VCO frequency is divided by a number N to produce a signal having a divided-down frequency. The signal having the VCO frequency is then mixed with the signal having the divided-down frequency to produce an output signal having an output frequency. Local oscillator leakage is reduced. Thus, the receiver or transmitter may operate in multiple wireless communication bands and modes and meet the associated specifications. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To improve a radio receiver's immunity to interference. SOLUTION: If the power level of a received signal meets or exceeds a predetermined power threshold, the low noise amplifier is by-passed, thus increasing the intercept point of a receiver. Alternative embodiments include the use of an RF power detector to control the front-end gain as a function of interference power. Continuous gain control allows the interference suppression and sensitivity of the receiver to be adjusted at lower signal levels than the switchable gain block. The processing device of the receiver measures the gain change in the IF signal power. If the change is less than the predetermined amount, the CDMA signal and interference power are below the noise floor and, therefore, the gain is increased. If the IF signal power change is greater than the predetermined amount, the interference is evident and the gain is reduced to reduce the intermodulation products. This process is used until the receiver is operating at the best compromise between interference and noise figure. COPYRIGHT: (C)2008,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide methods and apparatus for amplifier predistortion and autocalibration. SOLUTION: Methods and apparatus for amplifier AM and PM predistortion and autocalibration are provided. AM and PM amplifier distortion can be corrected using predistortion. The AM and PM distortion characteristics of the amplifier are determined using an autocalibration technique. The amplifier characteristics can be stored in distinct look up tables (526, 712). Alternatively, the inverse of the amplifier characteristics can be stored in distinct look up tables. Signals that are to be amplified are featured in polar format having a phase component with a normalized magnitude and a magnitude component. The phase component can be predistorted by applying the inverse of the PM distortion characteristics to the signal. Similarly, the magnitude component can be predistorted by applying the inverse of the AM distortion characteristics to the signal. The predistorted phase component can be amplified using the previously characterized amplifier. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for increasing receiver immunity to interference.
    SOLUTION: The power level of a received signal is detected. If the power level meets or exceeds a predetermined power threshold, a low noise amplifier 703 is provided with a bypass route 730, thus increasing an intercept point of the receiver components. By using an RF power detector, the front-end gain as a function of jammer power is controlled. The sensitivity of the receiver is adjusted at a lower signal level than a switchable gain block by a predetermined amount. The receiver processing section measures the gain change in the IF signal power. If the change is less than the predetermined amount, the CDMA signal and jammer power are below the minimum noise and, therefore, the gain is increased. If the IF signal power change is greater than the predetermined amount, the interference is evident and the gain is reduced to reduce the intermodulation products. This process is used until the receiver operates at the best compromise between interference and noise figure.
