Claim of US Patent No. 11,032,826

1. A wireless communication system, comprising:a plurality of wireless networks simultaneously operating over a same RF spectrum band, at least one network of the plurality of wireless networks comprising a secondary network having at least one radio frequency (RF) transmitting node, wherein each of the at least one radio frequency (RF) transmitting nodes is capable of estimating a change in the average throughput of a transmission of the at least one radio frequency (RF) transmitting node on at least one primary network of the plurality of wireless networks, wherein each at least one radio frequency (RF) transmitting node comprises:
a modulation classifier that estimates from a sensed wireless signal, a modulation scheme used in a transmission of a wireless signal that carries information over a wireless link that has been established in the at least one primary network of the plurality of wireless networks; and
a throughput estimator which determines, without exchanging information between networks of the plurality of wireless networks, a forward error control (FEC) channel coding rate for the sensed wireless signal, wherein the at least one radio frequency (RF) transmitting node in the secondary network uses information from the throughput estimator to determine a transmitting power level of the transmission of the at least one radio frequency (RF) transmitting node that does not reduce the throughput over the wireless link associated with the sensed wireless signal sent and received in the primary network by more than a prescribed target maximum value.
