AI Technical Summary

Problems solved by technology

It is unclear how these metrics can be achieved using the existing architecture of CMOS devices, so the dynamic range, sensitivity, and multimode interleaving of multibit analog-to-digital converters (ADCs) and digital-to-analog converters (ADCs) are essentially a comparison difficult question

Embodiment Construction

[0014] The following discussion of embodiments of the invention with respect to cellular radio architectures is merely exemplary in nature and in no way intended to limit the invention or its application or uses. For example, the radio architecture of the present invention is described as having application for vehicles. However, as will be appreciated by those skilled in the art, the radio architecture may have applications other than automotive applications.

[0015] In addition to cellular wireless technologies, the cellular radio architecture discussed herein is also applicable to, for example, WiFi (IEEE802.11) technologies. Further, the cellular radio architecture is presented as a full-duplex wireless system, ie a wireless system capable of both transmitting and receiving. For receive-only wireless services such as Global Positioning System (GPS), Global Navigation Satellite System (GNSS), and various entertainment radios such as AM / FM, Digital Audio Broadcasting (DAB)...

Abstract

A method and apparatus for dynamically modifying filter characteristics of a Delta-Sigma modulator are disclosed. The system is used for wide bandwidth radio system designed to adapt to various globalradio standards and, more particularly, to a cellular radio architecture that employs a combination of a single circulator, programmable band-pass sampling radio frequency (RF) front-end and optimized digital baseband that is capable of supporting all current cellular wireless access protocol frequency bands.

Description

technical field [0001] This application relates generally to wide-bandwidth radio systems designed to accommodate various global radio standards, and more specifically to a radio frequency (RF) front-end that employs a single circulator, programmable bandpass sampling, and capable Combined cellular radio architecture with optimized digital baseband for protocol frequency bands. Background technique [0002] Traditional cellular phone adoption has been achieved by integrating multiple different radio front-end and baseband processing chips into platforms such as tri-band or quad-band user handsets supporting Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), etc. Different operating modes and bands supported in hardware. Although known cellular receivers have integrated some antennas and baseband data paths, the state of the art for large-scale mobile vehicular radio deployments nonetheless is multiple static channelization approaches. This ...
