摘要： The embodiments herein relates to a method in a base station (101) for transmitting an UpLink Transmit Power Control, UL TPC, command to a user equipment (103) in a communications network (100). The base station (101) obtains a measurement of a distortion of a signal received from the user equipment (103). The signal is associated with a power to be controlled. The base station (101) determines that the signal is unreliable if the distortion measurement is above a threshold or determining (308) that the signal is reliable if the distortion measurement is below the threshold. The base station (101) transmits a first UL TPC command to the user equipment (103) when the signal is determined to be unreliable or transmits a second TPC command to the user equipment (103) when the signal is determined to be reliable.

摘要： The embodiments herein relate to a method in a network node comprising a rake receiver (300) for enabling SNR error compensation. The rake receiver (300) obtains (202, 203, 602) a SNR gain error of a signal associated with an antenna (301). The rake receiver (300) multiplies (204, 205, 603) a first sub signal with a first weight parameter, and the first sub signal with the SNR gain error, thereby providing a first rake finger value. The rake receiver (300) multiplies (204, 205, 604) a second sub signal with a second weight parameter, and the second sub signal with the SNR gain error, thereby providing a second rake finger value. For the first antenna (301), the rake receiver (300) combines (206, 207, 605) the first rake value with the second rake value. Further, it decodes (208, 209, 607) the combined first rake finger value and the second rake finger value.

摘要： The present invention helps to mitigate and reduce the amount of interfering (e.g. RF leakage) that enter the phase detector of a phase locked loop by acting as a less than perfect sampler. This is accomplished by introducing a time jitter to the signal edges that enter the phase detector input. A phase detector can also be made to act as a less than perfect sampler by intentionally introducing an interfering signal. For example, a small interfering analog signal can be introduced with a different frequency from the reference frequency already present in the PLL. The interfering signal will cause the stable internal signal to vary slightly in time at the rate of the interfering signal frequency. It is this signal variation and jitter introduced on the signal edges entering the phase detector input that induces the phase detector to act as a less than perfect sampler.

摘要： A communication device includes a transmitter configured to provide a transmitted output signal, and a power detector configured to receive reference signals from a waveform generator associated with the transmitter, and to receive a portion of the transmitted output signal from the transmitter. The power detector is further configured to compare the reference signals with a digital representation of the portion of the transmitted output signal, and calculate a gain associated with the transmitter based on the comparison. The power detector is also configured to receive, from the waveform generator, a root mean square (RMS) value of the reference signals, and generate an estimate of the output power of the transmitter based on the calculated gain and the root mean square (RMS) value of the reference signals.

摘要： Methods and circuits for synthesizing two or more signals phase-locked to a common reference frequency signal are disclosed. In one embodiment, a method comprises generating first and second output signals (350, 370) phase-locked to a reference clock signal, using first and second phase- locked loop circuits (200', 200' '). In response to a detected frequency error in the first output signal, the first output signal (350) is corrected by adjusting a frequency-division ratio in the first phase-locked loop circuit. The second output signal (370) is corrected, separately from the correction to the first output signal, by adjusting a frequency-division ratio in the second phase-locked loop circuit, using an adjustment parameter calculated from the detected frequency error. In another exemplary method, first and second output signals are generated as described above, using first and second phase-locked loop circuits. The first output signal is corrected by adjusting a frequency-division ratio in the first phase-locked loop circuit and generating a control signal (360) to adjust the frequency of the reference clock signal, in response to detected frequency error in the first output signal. Because the second output signal (370) is derived from the common reference clock signal, adjustments to the reference clock frequency (FREF) will also adjust the frequency of the second output signal. Additional adjustments to the second output signal (370) may be applied in some embodiments by adjusting a frequency-division ratio in the second phase-locked loop circuits. Circuits for implementing the described methods are also disclosed.

摘要： In a dual-carrier, double-conversion Orthogonal Frequency Division Multiplexing (OFDM) receiver a frequency synthesizer generates a first local oscillator signal for the first down-conversions stage of the receiver. A frequency divider is used to derive a second local oscillator signal from the first local oscillator signal, thus eliminating the need for a separate frequency synthesizer for the second down-conversion stage. A controller determines the frequency of the first local oscillator signal and a divisor M to align subcarrier grids for said first and second baseband signals with DC.

摘要： Systems and methods for mitigating crosstalk between controlled oscillators of Phase-Locked Loops (PLLs) are disclosed. In one embodiment, a system includes a first PLL including a first controlled oscillator and a second PLL. The system further includes a compensation signal generator adapted to generate a compensation signal at an offset frequency that is approximately equal to an offset between output frequencies of the first and second PLLs and apply the compensation signal to the first controlled oscillator such that the output signal of the first controlled oscillator is modulated by the compensation signal. An amplitude and a phase of the compensation signal are such that, when the compensation signal is applied to the first controlled oscillator, a crosstalk signal output by the first controlled oscillator resulting from crosstalk from the second controlled oscillator of the second PLL to the first controlled oscillator of the first PLL is mitigated.
