Method and/or system for communication
View Patent ↗An apparatus includes a transmitter, receiver or transceiver to couple to a communication link. An input receives one or more signals for a desired power level of the transmitter, receiver or transceiver. A power supply provides power to the transmitter, receiver or transceiver depending on at least the one or more signals.
1. A system comprising:
a first transmitter or transceiver to operate at an output power;
a second receiver or transceiver to operate at a receive power;
a communication link to connect the first transmitter or transceiver to the second receiver or transceiver;
a processor to determine the output power and determine receive power based on predetermined instructions; and
a loopback module configured to monitor transmission performance of the system,
wherein at least one of the output power and the receive power are optimized for the communication link based on at least the monitored transmission performance.
2. The system of claim 1 , further comprising a memory to store the output power and the receive power.
3. The system of claim 2 , wherein the memory comprises a Read Only Memory (ROM).
4. The system of claim 1 , further comprising one or more fuses or fuse-based circuits to store the output power and the receive power.
5. The system of claim 1 , wherein the processor is configured to dynamically determine the output power and the receive power.
6. The system of claim 5 , wherein the processor is configured to monitor transmission performance and to iteratively optimize the output power and the receive power to achieve a predetermined data transmission performance.
7. A method of optimizing the power for a first transmitter or transceiver connected via a communication link to a second receiver or transceiver, the method comprising:
monitoring transmission performance at the first transmitter or transceiver and the second receiver or transceiver; and
iteratively optimizing the output power for the first transmitter or transceiver and the receive power for the second receiver or transceiver, to achieve a predetermined data transmission performance, wherein the iteratively optimizing comprises
determining a power curve by adjusting the output power for the first transmitter or transceiver and the receive power for the second receiver or transceiver over a range of transmit powers while keeping the transmission performance at the predetermined transmission performance based on the monitoring,
after adjusting the output power and receive power over the range of transmit powers, selecting a point on the power curve where combination of output power for the first transmitter or transceiver and the receive power for the second receiver or transceiver is minimum for the predetermined transmission performance, and
setting the output power for the first transmitter or transceiver and the receive power for the second receiver or transceiver at values that correspond to the selected point.
8. A system comprising:
a transmitter to operate at an output power;
a receiver to operate at a receive power;
a communication link to connect the transmitter the receiver; and
a processor to determine the output power and determine the receive power based on predetermined instructions, wherein
at least one of the output power and the receive power are optimized for the communication link,
the processor is configured to
dynamically determine the output power and the receive power,
monitor transmission performance, and
iteratively optimize the output power and the receive power to achieve a predetermined data transmission performance by adjusting currents in the transmitter and the receiver.
9. The method of claim 7 , further comprising:
determining a minimum output power of the first transmitter or transceiver, wherein determining comprises
setting the receive power at a maximum receive power value,
setting the output power at a maximum output power value,
after setting the output power and the receive power, reducing the output power until the data transmission performance just meets the predetermined data performance, wherein the minimum output power comprises the output power when the data transmission performance just meets the predetermined data performance; and
determining a minimum receive power of the second receiver or transceiver, wherein determining comprises
setting the receive power at the maximum receive power value,
setting the output power at the maximum output value, and
after setting the output power and the receive power, reducing the receive power until the data transmission performance just meets the predetermined data performance, wherein the minimum receive power comprises the receive power when the data transmission performance just meets the predetermined data performance.
10. The method of claim 9 , wherein the range of transmit powers comprises a range of transmit powers between the maximum output power value and the minimum output power of the first transmitter or transceiver.
