POWER COMPENSATION IN MULTI-CARRIER TRANSMITTERS

摘要

A transmitter and method for transmitting a communication signal having at least a first carrier and a second carrier. The transmitter includes a scaling factor estimator configured to estimate a first power scaling factor for the first carrier and a second power scaling factor for the second carrier; and a gain controller configured to adjust at least one of a power of the first carrier based on the first power scaling factor and a power of the second carrier based on the second power scaling factor, wherein a sum of the adjusted powers of the first and second carriers is less than or equal to a maximum transmission power, and a power imbalance between the adjusted powers of the first and second carriers is less than or equal to a maximum power imbalance.
