Transceiver circuit employing shared digital signal processing circuitry for communicating radio frequency (RF) analog communications signals received by a remote unit in a wireless distribution system (WDS)

摘要

Embodiments of the disclosure relate to a transceiver circuit employing shared digital signal processing circuitry for communicating radio frequency (RF) analog communications signals received by a remote unit in a wireless distribution system (WDS). A transceiver circuit includes downlink digital signal processing circuitry that receives and processes a downlink digital communications signal(s) having a first downlink digital baseband signal and a second downlink digital baseband signal. A first downlink analog signal path and a second downlink analog signal path share the downlink digital signal processing circuitry. The first downlink analog signal path generates a first downlink analog RF communications signal. The second downlink analog signal path generates a second downlink analog RF communications signal. By sharing the downlink digital signal processing circuitry, it is not necessary to add additional downlink digital signal processing circuitry, thus helping reduce digital component costs of the transceiver circuit.
