Abstract:
Embodiments of the disclosure relate to reducing out-of-channel noise in a wireless distribution system (WDS). A digital filter in a remote unit is configured to suppress out-of-channel noise in a downlink digital communications signal based on at least one filter configuration parameter received from a control circuit. The control circuit is configured to determine the filter configuration parameter based on physical characteristics of the downlink digital communications signal. By suppressing the out-of-channel noise of the downlink digital communications signal, it is possible to provide a downlink RF communications signal communicated from the remote unit that complies with a spectrum emission mask (SEM). Further, by suppressing the out-of-channel noise at the remote unit, it is not necessary for a central unit to perform digital filtering before distributing the downlink digital communications signal to the remote unit, thus helping reduce complexity, cost, physical size, and power consumption of the central unit.

Claim (Index 1):
A wireless distribution system (WDS), comprising:\n a central unit configured to communicate one or more downlink digital communications signals to a central unit communications interface communicatively coupled to at least one downlink communications medium; and a plurality of remote units, each comprising:\n a remote unit communications interface communicatively coupled to the at least one downlink communications medium to receive a downlink digital communications signal among the one or more downlink digital communications signals communicated by the central unit; \n a digital filter configured to:\n receive the downlink digital communications signal in a predefined frequency channel having a predefined bandwidth for at least one communications service; and \n output a modified downlink digital communications signal based on the downlink digital communications signal and at least one filter configuration parameter received from a control circuit configured to determine the at least one filter configuration parameter based on one or more physical characteristics of the downlink digital communications signal to suppress out-of-channel noise in the downlink digital communications signal; \n \n a digital-to-analog converter (DAC) configured to convert the modified downlink digital communications signal into a downlink radio frequency (RF) communications signal; and \n a power amplifier configured to generate an amplified downlink RF communications signal based on the downlink RF communications signal for communication to one or more client devices in the WDS; \n wherein the digital filter is further configured to suppress the out-of-channel noise in the downlink digital communications signal to provide for the amplified downlink RF communications signal to comply with a spectrum emission mask (SEM) for the at least one communications service.
