In this paper, we propose a low-complexity carrier frequency offset (CFO) estimation algorithm for OFDM based wireless LAN, IEEE 802.11a. The complexity of the arctangent operation to calculate the argument of auto-correlation for CFO estimation is reduced by a novel range pointer method. The proposed algorithm estimates fine CFO value first and then based on the fine CFO value, simple criteria is...
In this paper, we present a timing synchronization scheme of the next generation IEEE 802.tin wireless LAN standard which is based on MIMO-OFDM technique. The proposed timing synchronization method takes two steps which consist of two modified auto-correlators. For coarse timing synchronization, a sliding window differentiator is used after a conventional auto-correlation in order to avoid plateau...
In this paper, a robust, low-complexity timing synchronization algorithm suitable for 5.9 GHz advanced dedicated short range communications (ADSRC) system and its efficient hardware implementation is proposed. Cross-correlation technique is used to detect the starting point of short training symbol and the guard interval of the long training symbol. The design is implemented in a Xilinx Vertex-II...
In this paper, a robust, low-complexity timing synchronization algorithm suitable for 5.9 GHz dedicated short range communications (DSRC) system is proposed. The proposed method uses cross-correlation technique to detect the starting point of both a short training symbol and the guard interval of the first long training symbol. This allows the proposed algorithm to have low-complex architecture. Compared...
