ABSTRACT:
A method and system for diversity transmission from a mobile station. Signals sent from a mobile station to a base station may suffer from fading. To combat this, diversity transmission is used to compensate for the effects of fading and destructive multi-path interference by sending two or more signals. Signals to be transmitted from the mobile station are split into a first split signal and a second split signal and diversified from one another. Diversification of the split signals may be accomplished by modifying the phase of either the first split signal, the second split signal or both the first and second split signal. The diversified signals may then be transmitted from a first and second antenna.
