Abstract
An adaptive digital baseband receiver is described in which operating parameters of the receiver, such as bit-widths and operating frequencies, are determined that achieve a target bit-error-ratio (BER) as a function of received signal-to-noise ratio (SNR) and interference levels in a wireless channel and enable the receiver to consume a minimum amount of power. Over consumption of power may be avoided due to a functional relationship between optimal resolution and input signal conditions. In exemplary embodiments, the adaptive digital receiver is provided that adjusts bit-widths and operating frequency at power efficient levels while meeting a target BER. Simulations can be used to determine a relation between bit-width, operating frequency, and input signal conditions, for example.
