    • Methods and a receiver of positioning a spurious signal for reducing the impact of the spurious signal on a received Orthogonal Frequency Division Multiplexing, OFDM signal, are presented. The method comprises determining the frequency of a spurious signal (steps 102, 204, 404), determining the frequency for the respective sub-carrier of the OFDM signal and the difference between the frequency of a sub-carrier and the frequency of a spurious signal (steps 104, 206, 406), and adjusting at least one of: the frequency of the first oscillator (step 208) and a parameter related to the frequency of a second oscillator, to decrease the frequency difference between a sub-carrier and a spurious signal (steps 106, 212, 408). By positioning a spurious signal at or near a sub-carrier frequency, the performance impact of the spurious signal is reduced, and the receiver performance improved.
    • 提出了一种定位杂散信号的方法和接收机,用于减少寄生信号对接收到的正交频分复用OFDM信号的影响。 该方法包括确定杂散信号的频率(步骤102,204,404),确定OFDM信号的相应子载波的频率以及子载波的频率与寄生信号的频率之间的差异 (步骤104,206,406),并且调整第一振荡器的频率(步骤208)和与第二振荡器的频率相关的参数中的至少一个,以减小副载波和第二振荡器之间的频率差 寄生信号(步骤106,212,408)。 通过在副载波频率处或附近定位杂散信号,减少了杂散信号的性能影响,并提高了接收机性能。

    • A frequency-converting sensor is provided for generating at least a radio frequency signal parameter, such as an electrical power value. The sensor comprises an analog receiving section configured to convert an input signal into corresponding I/Q components using a local oscillator frequency, an analog to digital converting unit configured to convert the corresponding analog I/Q values into digital I/Q values, and a digital processing unit. The digital processing unit comprises an adjustable filtering unit configured to select a sideband of the digital I/Q values, and a calculating unit configured to calculate the radio frequency signal parameter from the I/Q-values of the selected sideband. A system is further provided for analyzing radio frequency input signal parameters, wherein the system incorporates a device under test, which generates the radio frequency signal, the sensor and a display device.
