Receiver circuit for receiving several signals, has antenna to receive multiple signals produced by modulating carrier waves having same frequency, where signal processing device is provided for processing and demodulating digital signals

摘要

The receive circuit has an antenna (10) for receiving multiple signals which are produced by modulating carrier waves, which possess a same frequency, in accordance with digital signals with different bit rates, which are emitted by the multiple systems. The circuit comprises a signal processing device for processing and demodulating the digital signals. The circuit comprises multiple digital filter mechanisms, from which each digital signal emitted by an appropriate system, out of the many systems, is extracted out of the demodulated signal that is emitted by the signal processing mechanism, based on a bit rate of the digital signal that is emitted by the appropriate system.
