Echo cancellation for a broadband distribution system |
摘要 |
A wideband signal distribution unit for receiving a plurality of inputs and having a plurality of outputs is provided. The distribution unit features a first combiner having an output and being connected to a first subset of the plurality of inputs. A second combiner having an output is connected to a second subset of the plurality of inputs. A phase shifting combiner having inputs each connected to the outputs of the first and second combiners supplies a combined signal to an output connected to a splitter which is connected to the plurality of signal distribution unit outputs. The phase shifting combiner is designed to apply a phase shift to one of its inputs.
