Patent ID: 7233591

Claim:
A power control system configured to control transmission energy of a first type of data and a second type of data punctured into the first type of data, comprising: an input that receives the first type of data and the second type of data; a decoder that separates the second type of data from the first type of data; an energy measurement circuit that measures energy of the second type of data; a power control processor that receives an indication of the energy of the second type of data and generates a power control command for the transmission energy of the first type of data based on the indication of the energy of the second type of data; transmission means for transmitting the power control command; a filter that filters a plurality of the received power control commands to provide an improved estimate of the received energy of the power control commands; power control bit processor that adjusts the energies of the received power control commands to compensate for energy adjustments made at the transmitter in response to a set of previously transmitted power control commands, wherein the power control processor estimates the most likely sequence of power control commands responded to by the transmitter, and adjusts the energies of the received power control commands to compensate for energy adjustments made at the transmitter in response to the estimates the power control commands received by the transmitter, and wherein the power control processor estimate the most likely sequence of power control commands responded to by the transmitter by comparing changes in the received energy of the received power control commands against expected changes in those commands, based on the set of previously transmitted power control commands, identifying suspicious responses to the previously transmitted power control commands and testing a set of hypotheses of receive power control commands in accordance with the identified suspicious responses.
