1. A method of determining a gain offset between transmission channels in a communication system, comprising the steps of:
- deriving a first set of channel estimates from symbols received through a first channel;
deriving a second set of channel estimates from symbols received through a second channel; and
determining the gain offset based on the first and second sets of channel estimates.

Abstract
Methods and apparatus are described for estimating a gain offset between two channels in a communication system. The gain offset arises from the system'"'"'s transmission of signals on the two channels at different powers. The estimated gain offset is used for determining a set of complex channel estimates.
