A New Air Interface OFDM-Based Access

Technique and IP-Based Transmission To fulfil the system requirements for next-generation systems with higher mobility and much higher user data rates, OFDM is a strong candidate for an air interface in these systems. A radio transmission system for the future generation communications must provide great flexibility and adaptivity at different levels, ranging from the highest (requirements of the application) to the lowest layer (the transmission medium, the physical layer, i.e., the radio channel). The current proposal focuses on the development of a system proposal for an air-interface and suitable multiple access techniques in an IP-based wireless system for future multimedia communications. The study will be based on a comparative and performance evaluation of existing and the newly developed techniques. Approximate duration is until June 2005. (Albena Mihovska)
