Low Complexity Decision Directed Channel Tracking for Mimo WLAN Systems
Chen, Ying; Jayalath, Anagiyaddage Dhammik; Abhayapala, Thushara
It is expected that the next generation wireless local area networks will be predominantly based on MIMO-OFDM physical layer. The performance of coherent MIMO-OFDM based systems critically depends on the availability of accurate channel estimations. Preambles, at the beginning of each packet, are used to estimate the channels in IEEE 802.1 In Systems. However, in mobile communication, when the channel is time varying, the channel variations within a given packet increases the packet error rate...[Show more]
