    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 modulation device includes a signal input for receiving a data stream to be modulated and a first and a second signal output. At least one first complex component is derived from the data stream in a coding device. A first and a second high-frequency signal are output via the signal outputs. The first and second high-frequency signals are derived from the at least one first complex component and are distinguished by the fact that the second high-frequency signal has a phase shift of substantially 90° with respect to the first high-frequency signal.
