Mathematics of Computation, Vol. 24, No. 111 (Jul., 1970), pp. 647-656 (10 pages) Quasi-Newton methods accelerate the steepest-descent technique for function minimization by using computational ...

Multipath is real and omnipresent, a detriment when GPS is used for positioning, navigation, and timing. The authors look at a technique to reduce multipath by using a pair of antennas on a moving ...
