Adaptive equalizer for digital cellular radio

摘要: The present invention provides a method of estimating parameters mobile radio channel which are used for providing the equalization and synchronization channel. is modelled as discrete number independent Rayleigh-faded propagation paths. First, relative delay each path estimated, using maximum likelihood methods. Using this information, associated time-varying weights then determined least-squares fit. This sufficient information to estimate impulse response actual equalizer obtained by inverting estimated response.
