Abstract
A ZF joint detection apparatus for a downlink receiver, the apparatus comprising: a channel estimator for estimating a channel impulse response of a multipath fading channel of a received signal; a channel equalizer for estimating a transmission signal by performing channel compensation and removing multipath interference by a deconvolution technique based on the estimated channel impulse response; and a user detector for detecting a symbol-level data sequence transmitted by a specific user by despreading the transmission signal estimated by the channel equalizer with a spreading code for the specific user and a scrambling code.
