dc.description.abstractIEEE 802.11ad uses mmWave technology for multi-gigabit wireless access networks. Multipath with large delay spread severely reduces performance due to insufficient guard interval. In this paper, we improve single-carrier IEEE 802.11ad receivers by proposing channel estimation and equalization methods for a frequency domain equalizer. Channel estimation is improved by leveraging on sparsity of the channel impulse response, while equalization is combined with an interference cancellation algorithm. The log-likelihood ratio demapper is also improved by correct power estimation of signal, interference, and noise. Simulation results show that the proposed methods are effective on channels whose length exceeds the guard interval.en
