System and method for dynamic sampling rate adjustment to minimize power consumption in wideband radios

摘要

A system and method that minimizes power consumption in wideband radios by dynamically adjusting the sampling rates of an analog-to-digital converter to the minimum sampling rate required to support the operation in a wideband mode and operation a narrowband mode. The sampling rate is controlled according to an operating mode whereby the sampling rate for a wideband operating mode is greater than the sampling rate for a narrowband operating mode. The wideband operating mode is a mode in which energy for an entire frequency band is received and sampled by the analog-to-digital converter and the narrowband operating mode is a mode in which only a portion of the entire frequency band is received and sampled by the analog-to-digital converter.
