Patent ID: 7860193

Claim:
In a method for adaptively generating an estimate for a location of a boundary of a symbol with respect to time in a wireless network where channels are associated with various noise and subject to multi-path effect, the improvement of obtaining an energy peak corresponding to an improved coarse estimation of a boundary between symbols in said network, comprising: a) receiving a symbol; b) performing a correlation with respect to the symbol; c) determining a peak energy with respect to the correlation; d) determining a magnitude value with respect to the located peak energy; e) determining an adaptive threshold for the symbol by multiplying the magnitude of the peak energy with a parameter, the parameter being dependent upon at least one channel condition; f) comparing the threshold with the correlation; g) determining an instance in time before the energy peak that the threshold is substantially similar to an energy within the correlation; h) utilizing the instance in time as the coarse timing estimate.
