| 发明名称 | Monitoring health of a predistortion system | ||
| 摘要 | At a current time, a current intermodulation content of a predistortion system is determined. An intermodulation ratio is determined using the current intermodulation content and a previous intermodulation content for the predistortion system. The previous intermodulation content is determined at a time previous to the current time. The determined intermodulation ratio is compared with stored intermodulation ratios. A warning is communicated in response to the comparing indicating the predistortion system is unhealthy. Apparatus and computer program products are also disclosed. | ||

| 主权项 | 1. A method, comprising: determining at a current time a current intermodulation content of a predistortion system; determining an intermodulation ratio using the current intermodulation content and a previous intermodulation content for the predistortion system, the previous intermodulation content determined at a time previous to the current time; comparing the determined intermodulation ratio with stored intermodulation ratios; and communicating a warning in response to the comparing indicating the predistortion system is unhealthy. | ||
