IEEE 802.11p is developed to support cooperative intelligent transport systems. In such systems, channel estimation a challenging problem due the channel's double dispersive nature. this paper, modified time domain reliable test frequency interpolation (M-TRFI) scheme for orthogonal division multiplexing with index modulation (OFDM-IM) systems proposed. Unlike OFDM, OFDM-IM can achieve better performance in vehicular communication environments. However, in-active subcarriers, more difficult...
Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is emerging as a robust technology, especially valued in vehicular communication scenarios for its resilience. In such dynamic environments, reliable channel estimation becomes critical to maintain system performance due the fast time-varying and double dispersion nature. Despite harsh conditions, OFDM-IM enhances by leveraging inactive sub-carriers convey additional information. However, these idle complicate...
