Abstract:
1. A mobile communication device comprising: a first antenna element arranged to receive first signals representative of first and second symbols encoded with a first channel coefficient; a second antenna element arranged to receive second signals representative of said first and second symbols encoded with a second channel coefficient; first and second delay lines operative to delay said first and second signals respectively; and a machine coupled to the first and second antenna elements and to the first and second delay lines and capable of executing instructions embodied as software; and a plurality of software portions, wherein one of said software portions is configured to supply a master rake module with the first and second delayed signals and with a pilot channel sequence and is further configured to up-sample said pilot channel sequence at chip rate in order to mix said pilot channel sequence with said second delayed signals to deliver correlated delayed signals and to determine first and second channel coefficient estimates from said first delayed signals and said correlated delayed signals; one of said software portions is configured to supply a slave rake module with the first and second delayed signals and with a scrambling code sequence and a spreading code sequence and is further configured to determine first and second auxiliary composite symbols from said first and second delayed signals, scrambling code sequence and spreading code sequence; and one of said software portions is configured to supply a combining module with said first and second auxiliary composite symbols and with said first and second channel coefficient estimates in order to determine first and second output signals representative of said first and second symbols respectively times the sum of said first channel coefficient estimate squared and second channel coefficient estimate squared.
