METHOD AND APPARATUS FOR RECEIVING DATA IN A COMMUNICATION SYSTEM

摘要

A method and an apparatus for receiving data in a communication system are provided to prevent deterioration of the system by detecting data by tracking an RLS(Recursive Least Square) algorithm channel and performing a sphere-decoding. An apparatus for receiving data in a communication system includes a plurality of feedforward filters(211,213,215), a plurality of decoders(221,223,225), a pair of feedback filters(231,233), a pair of adders(241,243), and a coupler(250). The feedforward filters(211,213,215) cancel interference signals included in each component of inputted signals. The feedforward filters(211,213,215) and the feedback filters(231,233) perform an RLS algorithm. The decoders(221,223,225) decode signals inputted in a sphere-decoding method. The couplers(250) decide the weight of the feedforward filters(211,213,215) and the feedback filters(231,233).
