This paper describes a novel architecture for building software wireless network interfaces. These interfaces, implemented in user-level software, run on oo-the-shelf PCs and replace all of the link and many of the physical layer functions typically implemented in dedicated hardware on a network interface card (NIC). They provide all of the processing needed to transform between wideband IF signals and network packets. Moving this functionality into user-level software has several advantages… 

An Architecture for Adaptable Wireless Networks

TLDR
The analysis shows that an adaptable physical layer can provide the best service to the application and that voice applications are able to better react to changing channel conditions and optimize physical layer performance using application specific parameters.

Next century challenges: RadioActive networks

TLDR
RadioActive networks, an adaptable wireless network architecture which draws on the strengths of software radios and active networks, are needed to meet the challenge of utilizing the spectrum as e ciently as possible given current channel conditions and in the most ective way for each application.

Software radio architecture with smart antennas: a tutorial on algorithms and complexity

TLDR
A wireless network with beamforming capabilities at the receiver which allows two or more transmitters to share the same channel to communicate with the base station and a joint beamforming and power control algorithm is implemented in a software radio smart antenna in a CDMA network.

Overview of Vanu Software Radio

TLDR
In Vanu Software Radio, most signal processing is done by general- Purpose or hybrid general-purpose/DSP processors, not by traditional digital signal processors or field-programmable gate arrays, and are expected to port easily to a wide range of future processors.

The application of software-radio in a point-to-point radio link receiver

TLDR

The road to 4G: two paradigm shifts, one enabling technology

TLDR
This work contends that two fundamental paradigm shifts must emerge if 4G is to succeed, and presents a new bandwidth sharing/allocation strategy, blending the best of traditional spectral allocation strategies with the emerging concept of ultrawideband wireless.

Multipass communication systems for tiled processor architectures

TLDR
An in depth look is taken of the Raw processor's tiled architecture as a general-purpose parallel processor particularly well suited to portable communications processing and the capability of tiled processors to maximize processing capabilities at the system block level, as well as the system architectural level.

TLDR
This thesis describes the implementation of a software-based frequency hopping twoway radio in which dedicated hardware is used only for wideband frequency translation and A/D/A conversion and the other radio functions are performed in software.

The SpectrumWare approach to wireless signal processing

TLDR
This paper uses processor and network memory to temporally decouple the sample streams from the software modules so that the bulk of the processing can be realized within virtual time programming environments.

Making Commodity PCs Fit for Signal Processing

Architectural Considerations for a New Generation of Protocols

TLDR
This paper identifies two new design principles, Application Level Framing and Integrated Layer Processing, and identifies the presentation layer as a key aspect of overall protocol performance.

Increasing network throughput by integrating protocol layers

TLDR
