Method and apparatus for channel estimation using plural channels |
March 18, 2008 |
| 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 estimation in a transmission diversity system |
June 26, 2007 |
| A method of channel estimation in a transmission diversity system includes observing phase differences between channel estimates in a diversity antenna, either determining whether a phase shift is a right half plane or a left half plane and calculating a left/right estimate, or deter |

Method and apparatus for estimation of phase offset between communication channels |
December 12, 2006 |
| Methods and apparatus are described for estimating a phase offset between two channels in a communication system to allow the use of both in determining a complex channel estimate. The phase offset arises from the system's rotation of only one of the two signaling channels prior to its |
