Abstract
Methods and systems are provided for adaptive guard interval (GI) combining. A signal carrying a symbol that is preceded by a guard interval (GI) that includes a portion of the symbol may be received, and a portion of the GI that is free from inter-symbol interference (ISI) may be determined. Only a part of the ISI-free portion of the GI may be selected. The selected part of the ISI-free portion of the GI may be less than a whole of the ISI-free portion. The selection may be configured based on a parameter that is applied to a function used in extracting the symbol. The parameter may be a timing adjustment, relative to a start of the symbol, applied to the function when extracting the symbol. Only the part of the ISI-free portion of the GI may then be extracted and combined with a corresponding portion of the symbol.
