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.

Description

Background technique [0001] Radiocommunication has become an integral part of everyday life in modern society, with a wide range of possible applications. Regardless of the application, unimpeded communication between a radio transmitter and a radio receiver is desired. Unimpeded communication may depend on a variety of factors including, for example, signal strength, noise caused by transmitter / receiver equipment, and interference power within the wireless communication channel through which the wireless signal is communicated. [0002] In radio receiver circuit design, high amplifier gain linearity and minimum noise figure are desired to meet specific design requirements for smooth radio communication. Noise is an undesirable byproduct of electronic devices and assemblies. One measure of noise factor is noise factor, which is a measure of how much noise is introduced into the amplified signal during the amplification process. The noise factor may be the ratio of the signa...
