  Abstract

In this paper, we propose a new channel estimation scheme which performs the reliability test based on the correlation with the previous and estimated channel values and the time domain interpolation technique in order to improve PER (packet error rate) and BER (bit error rate) in IEEE 802.11p WAVE (Wireless Access for Vehicular Environments) systems. In the proposed scheme, the correlation between the previous and estimated channel values is calculated and then the estimated channel value is updated only if the correlation is bigger than the predefined threshold per every OFDM (orthogonal frequency division multiplexing). Otherwise, the channel value is re-estimated through time-domain and frequency-domain interpolation, respectively, and the final channel value is updated through the correlation between the estimated and the previous channel values. The proposed method can reduce the demapping error and improve the accuracy of the reliability test. In addition, it can improve channel estimation accuracy and PER performance by time-based interpolation.
