Pilot Design based Channel Estimation for IEEE 802.11ad Wireless Communications at 60 GHz

Rajarshi Banerjee , B.Priyalakshmi and T.Rama Rao

IEEE 802.11ad is an enhancement to the IEEE 802.11 family standard, that enables multi-gigabyte wireless communication in 60 GHz. In this paper, we propose a unique pilot design and corresponding channel estimation method for a frequency selective fading 60 GHz channel. It is shown that in our proposed channel estimation the number of pilot subcarrier are fixed in one OFDM symbol, but the pilot tone gets changed every 50 OFDM symbols, the channel experiencing through frequency selective fading. The results of our proposed channel estimation shows that the channel error rate decreases with increasing SNR minimizes the noise of the channel.
