摘要： A receiver arrangement with AC coupling is specified in which a filter arrangement (3) is provided in a baseband signal processing chain in a homodyne receiver and can be switched between at least two high-pass filter cut-off frequencies. In this case, a brief changeover is made to a higher cut-off frequency when varying the gain of a low-noise baseband amplifier (2), for example when the received field strength changes, during the reception mode. The described arrangement allows changes to be carried out to the gain in baseband during the normal reception mode. The present receiver is accordingly suitable for code division multiple access methods, such as those which are provided in the UMTS Standard.

摘要： An apparatus provides a baseband signal for exploiting receive antenna diversity by means of a digital baseband processor. The apparatus includes a combiner configured to temporally alternately select at least one sample of a first received signal corresponding to a first receive antenna and at least one sample of a second received signal corresponding to a second receive antenna and to interleave the selected samples of the first and second received signal to obtain a temporally continuous stream of samples of a baseband representation of a combined signal at an output of the combiner as the baseband signal for exploiting receive antenna diversity.

摘要： A power control system includes a reference path filter used to suppress high frequencies in an input signal and generate a filtered envelope signal, a reference path amplifier to scale the filtered input signal based on a gain signal and generate a reference signal, a signal path amplifier to amplify an RF modulated signal and generate a signal path output signal scaled by a gain of an actuator signal, and a power detector to detect a power associated with the signal path output signal. The system includes an ADC to receive, pre-filter and convert the detected envelope signal into a measurement signal, and a comparator block to receive the reference signal and the measurement signal, and generate an error signal based on the difference, and a controller to generate the actuator signal for controlling the gain of the signal path amplifier based on the error signal.
