多载波发射机中的功率补偿
摘要：
本公开涉及多载波发射机中的功率补偿。本文公开了用于发送具有至少第一载波和第二载波的通信信号的发射机和方法。该发射机包括：缩放因子估计器，被配置为估计针对第一载波的第一功率缩放因子和针对第二载波的第二功率缩放因子；以及增益控制器，被配置为调整第一载波的功率和第二载波的功率中的至少一项，其中调整第一载波的功率基于第一功率缩放因子，调整第二载波的功率基于第二功率缩放因子，其中第一载波和第二载波的经调整的功率之和小于等于最大传输功率，并且第一载波和第二载波的经调整的功率之间的功率失衡小于等于最大功率失衡。
摘要（英）：

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.
