Abstract: Systems and methods for memory-efficient storage and extraction of maximum power reduction (MPR) values in two-carrier wireless data systems are presented. A wireless broadband device can operate under the HSUPA Category 9 standard, in which two carriers can be employed for data uplinks. Due to power saturation, interference, and other factors, transmission output power is limited to various levels depending on channel configuration. Under previous standards using one carrier, the maximum power reduction (MPR) needed to address those issues could be stored on the device, since the total number of MPR values was limited. With the introduction of dual carriers in HSUPA-9, storing all possible MPR values is no longer feasible. Platforms and techniques are disclosed which allow accurate generation of MPR values in a two-carrier system, utilizing the 2nd, 4th, and 6th moments of the complex signals to derive MPR values without attempting to store all possible carrier combinations.
