Abstract
A terminal including a transceiver, an analog-to-digital converter and control circuitry. The transceiver receives a stream of bursts from a plurality of units. One of the units is an electronic device. The analog-to-digital converter receives an upstream burst from the transceiver during an active time slot. The upstream burst is one of the bursts. In response to sampling the upstream burst at a sample rate, the analog-to-digital converter converts the upstream burst from an analog waveform into a sequence of digital values. In response to a coefficient for the electronic device being a default coefficient, the control circuitry stores the digital values into memory during the active time slot.
Claims20
An apparatus comprising:
- a transceiver configured to:
- receive a stream of bursts from a plurality of units, one of the units being an electronic device;
- an analog-to-digital converter configured to:
- receive an upstream burst from the transceiver during an active time slot, the upstream burst being one of the bursts, and
- convert, in response to sampling the upstream burst at a sample rate, the upstream burst from an analog waveform into a sequence of digital values;
- and
- control circuitry configured to:
- store, in response to a coefficient for the electronic device being a default coefficient, the digital values into memory during the active time slot.
A method comprising:
- receiving, by a transceiver, a stream of bursts from a plurality of units;
- receiving, by an analog-to-digital converter, an upstream burst from the transceiver during an active time slot;
- sampling, by an analog-to-digital converter, the upstream burst at a sample rate;
- converting, by the analog-to-digital converter in response to sampling the upstream burst, the upstream burst from an analog waveform into a sequence of digital values;
- and
- storing, by control circuitry in response to a coefficient for an electronic device being a default coefficient, the digital values into memory during the active time slot,
- wherein one of the units is the electronic device, and
- wherein the upstream burst is one of the bursts.
A network comprising:
- a terminal comprising a transceiver, an analog-to-digital converter and control circuitry,
- wherein:
- the transceiver is configured to receive, during an active time slot, a burst of information from an electronic device,
- the analog-to-digital converter is configured to convert, in response to sampling the burst at a sample rate, the burst from an analog waveform into a sequence of digital values;
- and
- the control circuitry is configured to store, in response to a coefficient for the electronic device being a default coefficient, the digital values into memory during the active time slot.
