Abstract :
In this paper bit-loading techniques have been applied to an H-OFDM system in an ad-hoc WLAN environment. The effect on the performance of the channel estimation errors has been analyzed showing that due to the proposed channel estimation procedure this effect is not very important. Also an upper-bound for the mean number of bits per OFDM symbol is derived. Those results show that the complexity introduced in order to manage the ad-hoc scenario and bit-loading techniques is worthwhile because of the good behaviour obtained.
