Abstract
Method and apparatus for packet detection is described. More particularly, a signal having sub-signals is received. The signal is quantized (“re-quantized”) to provide a quantized signal to processing units, where the quantized signal is a sequence of samples. A cross-correlation is done between the sequence of samples and a reference template, including totaling partial results from the processing units to provide a result. The result is a symbol timing synchronization responsive to the cross-correlation, which is provided in part by combining by addition or subtraction a regression vector obtained from the sequence of samples and a coefficient term vector obtained from the reference template.
