Device and method for spectrally shaping a transmission signal in a radio transmitter |
摘要 |
A device for spectrally shaping a discrete-value transmission signal, in a radio transmitter, includes one input for receiving an in phase component of the transmission signal and a further input for receiving a quadrature component of the transmission signal. The device also includes a filter circuit with a plurality of multipliers. A multiplexing unit is located in the signal path before the filter circuit, and a demultiplexing unit is located in the signal path after the filter circuit.
