Systems and methods are disclosed that provide a closed loop power control system including adaptively adjusting the desired target SINR over time so as to ultimately achieve a feasible SINR. In one implementation, a method is provided of optimizing uplink closed loop power control in a RAN in which one or more base stations each service a plurality of mobile stations, including: determining a power level for each mobile station for its respective uplink transmissions, including measuring a current achieved SINR for each mobile station; and for each mobile station, adjusting the power level to be sufficiently high to meet desired transmission characteristics but not so high as to cause unnecessary interference with transmissions from other mobile stations, by adjusting a desired target SINR based on factors selected from the following: current and prior achieved SINRs, current and prior interference measurements, and current and prior transmission power control commands.

Devices and methods capable of addressing filter responses are disclosed. For example, a method for compensating a first low-pass filter and a second low-pass filter is disclosed. The method includes injecting a reference tone fand a cutoff tone finto the first low-pass filter, and measuring respective filter responses of the reference tone fand the cutoff tone fwhile changing capacitor codes that control a cutoff frequency of the first low-pass filter until a first capacitor code Iis determined that most accurately causes the first low-pass filter to utilize a desired cutoff frequency f, performing a similar operation for the second low-pass filter until a second capacitor code Qis determined, and calibrating for mismatch between the first low-pass filter and the second low-pass filter.
