  • Patent number: 8285203
    Abstract: A satellite communications system has a hub terminal which communicates with a remote terminal through a satellite. The hub terminal 100 includes a transmitting modulator, power booster, up-converter and Power Amplifier (PA), and a transmitting station. The transmitting modulator generates a modulated signal, which is output to the power booster. The power booster receives the modulated signal and generates a spectral replication of the signal. The signal is then up-converted and amplified, and transmitted as an uplink signal to the satellite via a transmitting antenna. A remote station antenna receives the corresponding downlink signal. Following LNB/LNA and down-conversion, the signal is passed to a diversity combiner. The diversity combiner aligns the replicated signals by frequency and phase and generates a power-boosted signal. Accordingly, the system enables the use of ultra small antennas by providing increased power.

  • Patent number: 8280421
    Abstract: A terminal device free of interference between an RACH and a PUSCH or the like even when a base station device with a large coverage is installed. In the device, a configuration number extraction unit (103) extracts a configuration number from a BCH received by a BCH reception unit (102). A control unit (104) determines the corresponding RACH format (the necessity of repetition, the CP length TCP, the second preamble length TPRE2, and the GT length TGT) according to the configuration number, notifies a repetition unit (109) of the result of the judgment of necessity of repetition, notifies the repetition unit (109) of the second preamble length TPRE2, notifies a CP addition unit (110) of the CP length TCP, and notifies a GT addition unit (112) of the GT length TGT. When the repetition unit (109) receives the notification of performing the repetition, it performs the repetition according to the second preamble length received from a TPRE2 determination section (154).

  • Patent number: 8271014
    Abstract: A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.

  • Patent number: 8255009
    Abstract: Portable electronic devices are provided with wireless circuitry. The wireless circuitry may include one or more sets of radio-frequency power amplifiers. The radio-frequency power amplifiers are used to amplify radio-frequency signals that are transmitted by the portable electronic devices. Each power amplifier may have multiple gain mode settings. Gain stages within the power amplifiers may be selectively enabled in accordance with the gain mode settings. When a higher level of gain is required, all of the gain stages may be enabled. When a lower level of gain is required, some of the gain stages may be disabled to conserve power. An adjustable power supply may be used to provide an adjustable power supply voltage to the power amplifiers. The adjustable power supply voltage can be reduced when it is desired to minimize power consumption at a particular gain mode setting. Gain mode and power supply settings may be adjusted simultaneously.

  • Patent number: 8249516
    Abstract: An output signal SHS is secondarily amplified by a high-frequency amplifier AMP3 and an output signal SHR is secondarily amplified by an AMP4 for which high-frequency side amplitude reducing means is taken. In this case, the AMP4 has small gain of a high-frequency region and its output SHR-2 is reduced in amplitude. However, a high-frequency noise has a frequency higher than that of a carrier wave SH and the amplitude of a noise NzB becomes smaller. The other output signal SHS is directly amplified by the wideband amplifier AMP3. The width of an SHS-2 and the width of the SHR-2 are adjusted by amplitude adjusting means throughout the whole region and then mutually added by both signals addition amplifying means again so that the amplitude of the output signal SHS is adjusted to the SHR-2, and a predetermined threshold value is set to extract the noises.
