SYSTEM AND METHOD FOR UTILIZING DIFFERENT KNOWN GUARD INTERVALS IN SINGLE/MULTIPLE CARRIER COMMUNICATION SYSTEMS

摘要

A system and method for a transceiver structure, where Different Known Guard Intervals (DKGI) (104,108,112) are appended to multiple, consecutive data blocks (102,106,110) and. are then used in combination with Channel State Information (CSI) (206), derived from the received DKGI, to restore cyclic convolution (208) in the time domain. Once restored, the CSI and cyclic convolution are transformed into the frequency domain by EFT processing to facilitate equalization of the channel through Frequency Domain Equalization (FDE). Through performance of time domain channel estimation, there is no need for pilot signals and related overhead, thus channel capacity is enhanced.
