Abstract
Increasing interest in mobile communication systems with high data rates and low complexity, demands heavily for an extensive research on communication techniques and their optimal implementation. The Orthogonal Frequency Division Multiplexing (OFDM) scheme has been quite extensively used in many communication standards. A hardware implementation of an OFDM based system faces more challenges with respect to the latency in the digital signal processing chain especially when used in the vehicular environment. A reduction in the latency thus becomes quite useful since the signal processing time should be as less as possible due to a quite restricted time for communication setup in the vehicular area, e.g. IEEE 802.11a/g, IEEE802.11p. The paper proposes a method to reduce the latency in such OFDM based systems by effectively combining the interleaving and a part of lFFT.
