摘要： Embodiments herein include a method for obtaining a calibration parameter for an antenna array. The antenna array comprises a first and a second radio module with respective associated antennas, wherein both radio modules comprise a main transmitter and a connected calibration receiver or both radio modules comprise a main receiver and a connected calibration transmitter. The method comprises: injecting a first calibration signal in the first radio module and measuring a first response to the first calibration in the first radio module. This injecting and measuring is repeated for all combinations of the first and second radio modules. Finally, a numerical value is calculated using the responses; a calibration parameter is calculated based on the calculated numerical value. Embodiments herein also include a corresponding antenna array, computer program and computer program product.

摘要： Switch-modulation of a radio-frequency power amplifier by-representing the input signal by the I-signal (1) and Q-signal (9) of the complex components (I+j−Q), and pulse width modulating the I-signal and the Q-signal separately to create a modulated I-signal pulse sequence (3a) and a modulated Q-signal pulse sequence (3b). Further, the pulses corresponding to negative sample values are time-shifted relative the pulses corresponding to positive sample values, and each pulse of the I-signal pulse sequence is delayed by introducing a delaying time shift.

摘要： Clipping a widely-separated, multi-carrier signal is effectively performed without having to use a high sampling speed. Clipping is performed in a first stage at a combined signal level, but with a predetermined carrier separation of at least twice the channel bandwidth (2CBW), followed by repositioning the carriers at baseband zero frequency. After clipping, carriers are placed at their respective center frequencies with full carrier separation reintroduced in a second stage. Iterative clipping stages smooth out signal reshaping and re-settled amplitudes for combined carriers.
