Abstract
Systems and methods are provided for implementing and using multiband transceivers. In a transmitter that comprises a plurality of transmit paths, a frequency spectrum that is used for transmission may be assigned to the plurality of transmit paths. Performance in each of the plurality of transmit paths may be monitored during transmission of signals, and based on the monitored performance, at least one of segmentation of the frequency spectrum and assignment of the segments to the plurality of transmit paths may be dynamically modified. Performance monitoring may be based on spectrum usage, peak to average power ratio (PAPR), and/or performance related criteria (e.g., threshold, timeout duration, etc.). Modifying operation of a transmit path may comprise disabling or enabling that transmit path. The frequency spectrum may be segmented such that each of the segments is uniformly sized, or such that at least one of the segments is sized differently.
