Patent ID: 8059746

Claim:
A process of detecting transmit diversity comprising: A. receiving a diversity encoded signal from a base station at an antenna of a mobile unit, the receiving occurring on a primary common control physical channel, and the signal carrying a message of information; and B. decoding the message carried by the received signal to determine transmit diversity signal encoding information contained in the message; C. the receiving including receiving a diversity encoded Level 3 message signal, and including: producing a first control signal corresponding to the Doppler rate of the received Level 3 message signal; producing two channel estimate signals in response to the first control signal and a diversity control signal indicating STTD diversity; enabling phase-correction of the Level 3 message signal by the two channel estimate signals in response to the diversity control signal; rake combining multipath data signals from the Level 3 message signal and the two channel estimate signals in response to the diversity control signal; and decoding the rake combined Level 3 message and producing the STTD diversity control signal indicating STTD diversity.
