Objective
The overall objective of the CODIT project is to explore the potential of code division multiple access (CDMA) for a future high capacity universal mobile telecommunication system (UMTS). An advanced system concept based on CDMA will be established including advanced radio technologies (radio interface, radio transceivers, etc) and advanced sub-system architectures (micro- and pico-cells, macro-diversity, fast and soft handover, frequency management, radio network planning methods, etc).
A system demonstrator (testbed) comprising mobile station, radio base station and a radio network controller will be designed and built in order to validate the CODIT system concept.
The overall objective of the research was to explore the potential of code division multiple access (CDMA) for a future high capacity universal mobile telecommunication system (UMTS). The research utilises and advanced system concept based on CDMA which includes advanced radio technologies (radio interface, radio transceivers, etc) and advanced subsystem architectures (microcells and picocells, macrodiversity, fast and soft handover, frequency management, radio network planning methods, etc).
The system concept is designed to meet the major requirements of a third generation UMTS which are:
handling of picocells, microcells and macrocells with a simple deployment of specturm resources allowing multiple operators as well as private networks;
indoor and outdoor operation with a high grade of service;
support of low power pocket terminals for high quality speech services;
easy access to (known) data networks;
variable bit rate bearer for advanced data services;
the ability to support a large number of users (50% penetration rate).
The system testbed is designed to demonstrate:
radio transmission performance in an interference limited system handover real time speech transmission;
data transmission speech capabilities (lower layers only);
radio protocols as far as required for call setup and handover.
Technical Approach
The CODIT project is divided into three phases:
- An analysis phase: producing a broad outline of the system concept by mid 1992.
- A system design phase: the system is designed and verified via computer simulation, and a testbed build.
- A test and validation phase: the complete testbed is integrated and verified and tests results evaluated. As a result, the specification of the system will be revised at the end of the project.
Key Issues
The CODIT system concept will meet the major requirements of a third generation UMTS which are:
- Handling of pico-, micro- and macro-cells with a simple deployment of spectrum resources allowing multiple operators as well as private networks.
- Indoor and outdoor operation with a high grade of service.
- Support of low power pocket terminals for high quality speech services.
- Easy access to data networks.
- Variable bit rate bearer for advanced data services.
- Ability to support a large number of users (50% penetration rate).
Expected Impact
The CODIT project will help to increase the understanding of CDMA and explore its potential for future mobile and personal telecommunications systems. The results of the project will form a valuable input to standardisation work on future generations of mobile radio communication systems in Europe (ETSI) and the world scene.
