Abstract
A system and method for time domain interpolation of signals for channel estimation. A method for computing channel estimates comprises storing symbols in a buffer, using time domain interpolation (TDI) for a first time to compute channel estimates for a set of sub-carriers of a symbol. The channel estimates are computed from the symbol and a first number of required symbols in the buffer. The method also comprises using TDI for a second time to compute channel estimates for the set of sub-carriers of a symbol. The channel estimates are computed from the symbol, a second number of required symbols in the buffer, and a buffered symbol used as a missing required symbol if the missing required symbol is not in the buffer.
