The first circuit is configured to receive a radio frequency (RF) signal at the gate of the first MOS transistor. The drain of the first MOS transistor is configured to output a first current that is proportional to the square of the input voltage of the RF signal while receiving the RF signal. The second circuit includes a second MOS transistor having a source configured to receive a first current from the first circuit. The second MOS transistor is biased in a triode region and has a channel resistance between the source and a drain. The second circuit is configured to output a voltage proportional to the value of the power of the RF signal received by the first circuit.

摘要： In a method for adjusting modulation on a network, a modulation profile of a network node on the network is set a specified density. A plurality of messages that are received at the network node are monitored on an ongoing basis. The modulation profile of the network node is updated continually based on the monitored messages. A determination is made that a predetermined class of messages is received incorrectly at the network node. The network node is disconnected from the network based on the incorrectly received predetermined class of messages and is reconnected to the network to initiate the network node on the network.

摘要： A method of reducing resource overhead attributed to preambles in a communication system includes transmitting, at a transmitter, one or more signals including a first packet. The first packet is transmitted in a first time-frequency grant including a first set of one or more subcarriers. The first packet includes a full preamble including reference signal information for determining a total channel estimate for every subcarrier to be used in transmission of the first packet. A second packet is transmitted in a second time-frequency grant including a second set of one or more subcarriers without a full preamble when a receiver configured to communicate with the transmitter can determine a phase offset between the transmitter and the receiver from the signals received at the receiver.
