Workshop Chairman: Prof. Willie Lu, Chief Architect of 4G-OWA SmartPhones

In the recent ITU WP8F meeting in Tokyo on future mobile communications beyond IMT-2000 (officially called “IMT-Advanced” by ITU), the delegates fully agreed that the IMT-Advanced (which is basically a 4G program by ITU) will be targeting converged common wireless and mobile communication platform which is technically in the primary scope of Open Wireless Architecture (OWA) initiatives.

An unified global standard of mobile communications becomes extremely difficult and almost impossible. An Open Wireless Architecture (OWA) based converged wireless platform will thus become reasonable and feasible in both business and technology, and therefore ITU IMT-Advanced will be targeting this direction in long run.

The future wireless and mobile communications will be shifted from the traditional transmission-specific technology to the interface-specific technology to be able to converge with the computer system architecture and support complete openness and simplicity for the future mobile phone.

Open Wireless Architecture (OWA) technology is the solution for the Fourth Generation wireless and mobile communications (4G) on the worldwide basis. OWA refers to the open broadband wireless platform that can support diverse wireless and mobile standards, and can integrate multiple wireless networks. To achieve this flexibility, OWA focuses on all aspects of a communication system such as RF (radio frequency), baseband processing, networking and application segments. The flexibility and adaptability required for the converged open wireless platform can be achieved by defining the open interface parameters for the OWA systems and sub-systems.

OWA helps in realizing global roaming facilities and seamless networking capabilities amongst different radio transmission technologies. It allows the network operators and subscribers to use third party solutions or user-defined solutions on their systems and to customize their systems according to their business models. Using OWA we can build systems which support multiple standards, multiple bands, multiple modes and offer diverse services to the customers.

OWA is different from SDR (software defined radio) as OWA basically maps various wireless standards into open interface parameters and maintain the system platform including RF, baseband, networks and applications an open architecture. Hence, in OWA systems, different modules (both hardware and software) can be from different vendors. It is similar to the open computer architecture in personal computer system and open network architecture in packet router system.

However, SDR is primarily a radio in which the operating parameters including inter alia frequency range, modulation type, and/or output power limitations can be set or altered by software in order to support different radio frequency bands and/or standards. Though SDR has been improved a lot to support re-configurability and flexibility, it is a closed architecture in coupling different radios into one broadband transceiver. In other words, SDR may consume much more power and spectrum in exchange of the system flexibility. From the business point of view, SDR is not a cost-effective solution in wireless communications.

Signal Processing, including digital baseband signal processing and radio frequency signal processing, is one of the most important parts of the OWA system implementations. The iPhone evolution from Apple Computer, the upcoming GPhone from Google and the next generation iPAQ from HP will all be constructed upon the OWA wireless convergence platform.

Therefore, this first OWA signal processing workshop is very timely and valuable for those who are actively involved in the research and development of the next generation wireless mobile communications.

Original contributions are invited on recent research and development of OWA signal processing technologies such as converged wireless processing platform, common baseband processing, common transceiver signal processing, open antenna array S/T processing, common air-interface processing, integrated wireless terminal processing, etc. The topics of interest within the scope of this workshop include (but are not limited to) the following:

• Open wireless processing architecture & modeling

• Converged wireless and mobility processing platform

• Dynamic spectrum access control processing

• Software definable air interface modules

• Open module interoperability and optimization

• Open RF, antenna and transceiver signal processing

• Common baseband signal processing architecture

• Multiple air-interfaces channel processing and resource management

• High performance, low power wireless multiprocessor platform

• Open interface definitions of converged wireless signal processing

• Signal processing techniques for smart phone platforms

• OWA system development and performance analysis

• Other OWA signal processing topics
