| 摘要 |
A power amplification system (200) for wireless communications monitors wireless signal sequences for worst case or problematic data patterns likely to cause the output voltage of a voltage converter supplying the power amplifier to drop. The signal sequences, which may be data within a single timeslot or data packet or across several timeslots or data packets, are detected by monitoring data patterns, either alone or in conjunction with monitoring characteristics of a power amplifier (202). Upon detection of triggering signal sequences, the output power level is reduced. Monitoring and control units (205a, 205b, 205c, 205d) are included within the voltage converter (201), the power amplifier (202), a baseband modulator (204), and/or a transmission line-up unit (203). |
