Abstract :
As a part of our project, we have developed a HiperLAN2 based OFDM system which works with a 70 GHz front end. The main purpose of this paper is to study optimum parameters in order to realize a new OFDM based system that enables at least more than 100 Mbit/s. By using the actual measured propagation data, basic robustness comparison in the multipath environment for both OFDM and single carrier PSK system is discussed to show how OFDM is suitable for the 70 GHz multipath environment in order to pursue high data rate transmission. For the conclusion of this paper, an example of parameter optimization is performed under a 70 GHz indoor multipath environment.
