Patent ID: 8385487

Claim:
A diversity receiver, comprising: first and second antenna for receiving first and second signals, the first signal comprising first and second consecutive symbols modified by a first channel coefficient, the second signal comprising the first and second symbols modified by a second channel coefficient; first and second signal delay means coupled respectively to the first and second antenna elements; a master Rake finger means for estimating the first and second channel coefficients, the master Rake finger, comprising: first and second inputs coupled respectively to the first and second delay means and first and second outputs respectively for estimates of the first and second channel coefficients; and first complex conjugate transforming means coupled to the second output for producing the complex conjugate of the estimated second channel coefficient; and a slave Rake finger for determining the first and second symbols, wherein the slave Rake finger comprises: first and second decoding means coupled respectively to the first and second delay means for producing respective first and second composite signals; second complex conjugate transforming means having an input for receiving the second composite signal and producing a complex conjugate of the second composite signal; parallel-to-serial conversion means for interleaving the first composite signal and the complex conjugate of the second composite signal and providing an interleaved signal output; and a space time transmit diversity derotator having inputs for receiving said interleaved signal output, the estimated first channel coefficient and the complex conjugate of the estimated second channel coefficient and for recovering the first and second symbols.
