Abstract:
A method of receiving data over a dispersive media, comprising the steps of:receiving, by a receiver apparatus, a signal communicated via a dispersive media, the signal comprising an unknown data segment that is preceded by a first known data segment and followed by a second known data segment; generating a replica of the first known data segment and the second known data segment; estimating channel characteristics existing at the time of transmission of the first known data segment by comparing the received first known data segment with its generated replica; estimating channel characteristics existing at the time of transmission of the second known data segment by comparing the received second known data segment with its generated replica; and using the estimation of the channel characteristics existing at the time of transmission of the first known data segment to estimate at least one symbol of the unknown data segment and using the estimation of the channel characteristics existing at the time of transmission of the second known data segment to estimate at least one symbol of the unknown data segment.
