High data rate transmission in an indoor environment is an important issue for the next generation of wireless communications systems. For high data rate links (155 Mbits/s) a large channel around 60 GHz has been allocated world-wide for unlicensed, dense wireless local communications. However this indoor channel is a fading channel and an improved modulation technique is required to obtain such high data rate. In this paper, we propose a comparison of two adaptive modulation techniques based on OFDM. Tests have been realized on simulated channels as well as real indoor channel.
