In this paper a novel scheme for OFDM guard interval adaptation is presented, that uses the frequency domain channel length indicator (FCLI) algorithm for estimating the length of the channel impulse response (CIR). In contrast to other schemes, our method does not require any time averaging to estimate the CIR length and is applicable in SISO and MIMO OFDM, with and without spectrum mask. By estimating the CIR length in an ad hoc manner our results show, that it is possible to instantaneously react on changing propagation environments and to significantly increase throughput without decreasing detection performance.
