10. The method of claim 9 wherein said ramp weights W(k)=2k-1, k=1 to L/N, and said normalization factor a1=N/[2L].
10. The method of claim 9 wherein said ramp weights W(k)=2k-1, k=1 to L/N, and said normalization factor a1=N/[2L]. 11. The method of claim 10 wherein said scaled, stored uniformly-weighted segment sums are accumulated with said ramp-weighted accumulated value to provide a correlator accumulator value, a normalization factor a2 is applied to said accumulator value to provide said correlator output signal, and said normalization value=1/N.
