    摘要: Receiver resources are allocated based on how subframes are allocated within in a frame between downlink and uplink transmissions and how often the receiver is expected to report feedback information associated with the downlink transmissions. Additional time is available for processing received data blocks if the feedback information derived from those blocks must be reported later than expected due to the unavailability of uplink subframes. According to one embodiment, received signals are processed by receiving transmission configuration information indicating how downlink and uplink subframes are allocated within a frame in the time domain. Based on the transmission configuration information, the receiver determines whether a delay that exceeds a feedback reporting interval assigned to the receiver will occur when reporting feedback information associated with the downlink subframes. Receiver resources are allocated based on whether a delay will occur when reporting the feedback information.

    摘要: A radio frequency transmitter is power controlled using a controlling system including an integrating controller, together with an inner and an outer control loop. A tracking signal supplied by the inner loop to the integrating controller of the outer loop is used to avoid windup problems when the transmitted power is saturated.

    摘要: A crash box for fastening a bumper beam on a vehicle, for example a passenger car, has a closed cross section. Its perimeter has at least two longitudinal portions (19,21), and each of them has a concave portion (20) that passes into convex portions (19,21) at both sides. The smallest distance from the centre (40) of the crash box to the concave portion is less than 12% shorter than the largest distance from this centre to any one of the adjacent convex portions.

    摘要: An apparatus, and a method performed by the apparatus, including a terminal with a front end receiver and analog filter (AF) operable throughout a bandwidth that is large enough to cover the total bandwidth used by different access technologies that the terminal supports. The terminal is operable to simultaneously extract from the output of a single front end receiver and AF the carrier frequencies and bandwidths of the different access technologies. This permits cell evaluation activity and an ongoing communication session to be conducted simultaneously with different access technologies on different bandwidths within the bandwidth of the analog filter and without interruption of the communication session.

    摘要: A method to linearize the characteristic of a Class-D amplifier is achieved, by compensating for the pulse-area-error, caused by a non-constant power-supply and similar circuit inconsistencies. A Class-D Amplifier typically converts the PDM (Pulse Density Modulated) input signal with a Sigma Delta Modulator and typically uses an H-Bridge as the Class-D power output stage. A fundamental idea is to keep the time-voltage area of every pulse constant. To achieve this, the circuit integrates the power supply voltage, starting with the PDM input pulse and stopping, when the defined time-voltage reference is reached. To compensate not only for power supply variations, but also for e.g. the voltage drop across the output devices, the integrator's input would be more directly reference to the actual voltage across the output load.

    摘要: A method for compensating for the pulse area error of a Class-D power amplifier is achieved; especially it compensates the variations in the supply voltage and similar dependencies. A Class-D Amplifier typically gets pulse coded digital input (PCM) and may comprise a Sigma Delta Modulator to generate the signals driving the power output stage, typically an H-Bridge. A fundamental idea of this invention is to measure the real area of the output pulses, where the area is defined as the pulse duration multiplied by the pulse voltage amplitude, and to compare it with the ideal nominal pulse area. The pulse area error is calculated and then subtracted from said amplifier's input data. Key element of this invention is the “Pulse Area Compensation Function”, which calculates said real pulse area (voltage amplitude multiplied by time), compares said real pulse area with said ideal pulse area and feeds the difference into the input of said Sigma Delta Modulator.

    摘要: An long-wavelength optical fiber amplifier includes an erbium doped optical fiber (EDF) for amplifying an input signal light having a wavelength in the range of 1580 nanometers (nm) using pump light, a pumping unit positioned in front of and to the rear of the erbium doped optical fiber, for supplying the pump light to the erbium doped optical fiber, and an amplified spontaneous emission (ASE) reflecting unit positioned in front of the pumping unit, for coupling backward amplified spontaneous emission generated in the erbium doped optical fiber to the long-wavelength input signal light and inputting again the same to the erbium doped optical fiber. Fewer laser diodes and optical devices are necessary in amplifying an signal light having a long wavelength, by providing a reflector for reflecting amplified spontaneous emission. Also, the gain is increased in the case when the power of an input signal is small.
