BASEBAND PROCESSING METHOD BASED ON SMART ANTENNA AND INTERFERENCE CANCELLATION

摘要

This invention discloses a baseband processing method based on smart antenn a and interference cancellation, which includes: A. making channel estimation to get channel response; B. picking up useful symbolic level signal from received digital signal by smart antenna beam forming based on the channel estimation; C. making signal reconstruction by using the got useful signal and adding scrambling code to get the chip level reconstructed signal; D. subtracting the reconstructed signal from received digital signal; E. executing steps B to D repeatedly to recover signal for all user. The method of the invention can solve various interference of multi-pa th propagation in CDMA system with smart antenna and get better results.
