20090110041 | Method and Device for Transmitter Calibration - A device for calibrating a digital communication station uses an initial ranging procedure for measuring channel parameters in a communication channel. The device comprises a communication emulator, a measuring device, and a calibrator. The communication emulator transmits a signal to the communication station which transfers the communication station into an initial ranging mode. The measuring device measures parameters of the signal transmitted by the communication station during an initial ranging cycle. From these measurements the calibrator calculates the necessary calibration adjustments to the communication station and adjusts it accordingly. | 04-30-2009 |
20090274203 | Measuring Method and Device for Evaluating an OFDM-Multi-Antenna Transmitter - A method provides for evaluating the power performance of an OFDM multi-antenna transmitter, wherein a sum signal formed according to the WiMAX standard and transmitted from the multi-antenna transmitter, which represents a superposition of a preamble transmitted signal from a preamble transmit antenna of the multi-antenna transmitter and of at least one transmitted signal from a further transmit antenna of the multi-antenna transmitter, is transmitted via a transmission channel. A test receiver is phase-synchronized relative to the preamble transmit antenna on the basis of a preamble of the preamble transmitted signal, and a relative phase error between the transmitted signals is determined on the basis of a modulation method used for the transmission channel, the preamble and the error-vector magnitude (SEVM) calculated from the sum signal. A device for implementing the method is also provides. | 11-05-2009 |
