Abstract
At a receiver in a spread spectrum communication system, a spread spectrum signal is received. The received signal is despread with a plurality of delayed versions of a pilot chip code. The delayed pilot chip code versions are centered around a center delay. The center delay is based on a left mass and a right mass. The left mass is a sum of the despread pilot signal versions having a delay less than the center delay. The right mass is a sum of the despread pilot signal versions having a delay greater than the center delay. Each despread pilot signal version is weighted and combined. The combined despread pilot signal is used to adjust a weight of each pilot signal version. The received signal is despread with delayed versions of a data chip code. Each despread data signal version is weighted by a particular weight of a corresponding one of the weighted pilot signal versions. The weighted despread data signal versions are combined to recover the data signal.
