Device with decision-driven channel estimation in a digital mobile connection

摘要

The apparatus include demodulation means arranged to receive inphase and quadrature phase input signals. A channel estimation means is provided for deriving a decision directed channel estimate from one or more signals which is used by the demodulation means for demodulating one or more of the signals transmitted over the same radio channel. The apparatus is for use in the demodulation of dual binary phase shift keying signals and various embodiments are possible, for example, and may be used in conjunction with pre-combining Rake architecture.
