In recent years OFDM has provided very high data rates in WLANs, while CDMA has successfully provided low data rate real time voice traffic in highly mobile cellular systems. Different combinations of OFDM and CDMA are expected to provide air-interfaces with optimal throughput for different contexts, which are defined by channel delay spread, user mobility, user density, etc. Any one particular combination will not meet the requirements optimally in all contexts. It is a great challenge when user devices need to operate in all contexts equally well with optimal use of resources. This is possible with flexible and adaptive receiver architecture and air interfaces. The goal of the cooperation of AAU and TCS is to investigate and propose such systems.
