Devices, systems and methods that reduce funneling noise in upstream data transmissions from modems providing the transmissions through respective RF legs connected to the node. Preferred devices and systems may include a node that is configured to selectively isolate respectively scheduled upstream data signals from noise present on any RF leg not propagating a scheduled upstream data signal.

Scheduler-directed source multiplexing for return path noise mitigation

Systems and methods for permitting DOCSIS 3.1 equipment to operate at higher frequencies than specified in the DOCSIS 3.1 standard. Exemplary systems may be capable of alternating between a first mode of operation that provides DOCSIS 3.1 compatible services and a second mode of operation providing a higher level of service than DOCSIS 3.1.

Systems and methods for upstream and downstream CATV plant capacity expansion

The generation of OFDM signals for DOCSIS 3.1 specification having a required number of subcarriers and subcarrier spacing can be based on a sampling rate that is modified from that defined by the DOCSIS 3.1 specification. In embodiments, the base sampling rate is defined as Fs=204.8*A MHz (A&#x3e;1), with a respective increase of basic IFFT size by factor A. In embodiments, the OFDM signal is sampled at a sampling rate of 204.8 MHz*A for an IFFT size of 8192*A (4096*A), where A&#x3e;1.

DOCSIS 3.1 standard signal generation

Methods, systems, and apparatus can provide a multichannel interpolator while optimizing circuitry reuse.
