BASEBAND PROCESSING METHOD BASED ON SMART ANTENNA AND INTERFERENCE CANCELLATION

摘要

This invention discloses a baseband processing method based on smart antennaand interference cancellation, which includes: A. making channel estimation togetchannel response; B. picking up useful symbolic level signal from receiveddigitalsignal by smart antenna beam forming based on the channel estimation; C.makingsignal reconstruction by using the got useful signal and adding scramblingcode to getthe chip level reconstructed signal; D. subtracting the reconstructed signalfromreceived digital signal; E. executing steps B to D repeatedly to recoversignal for alluser. The method of the invention can solve various interference of multi-pathpropagation in CDMA system with smart antenna and get better results.
