  • Imbalanced transmission combining at radio base station
    Patent number: 8515377
    Abstract: A radio base station (20) comprises an antenna (22); a first power amplifier (241) configured to receive a first carrier signal; a second power amplifier (242) configured to receive a second carrier signal; and an imbalanced combiner (30). The imbalanced combiner (30) is configured to apply a power imbalanced combined signal to the antenna. The power imbalanced combined signal has a power imbalance between a first power level of the first carrier signal and a second power level of the second carrier signal as transmitted from the antenna (22).

  • Apparatus, and associated method, for calibrating a device
    Patent number: 5870001
    Abstract: Apparatus, and an associated method, for calibrating a device responsive to values of a reference signal. The reference signal may be subject to short-term disturbances. In one implementation, a cellular radio base station utilizes a Stratum-2 oscillator to which to phase-lock a base station VCO. Compensation is made for the aging of the Stratum-2 oscillator, thereby to provide a regulation signal causing the VCO to exhibit acceptable short-term and long-term frequency stability characteristics.
