DEVICE AND METHOD FOR ELIMINATING CODE INTERFERENCE OF CODE DIVISION MULTIPLE ACCESS COMMUNICATION SYSTEM

摘要

PURPOSE: A device for eliminating the interference that an orthogonal code causes to a quasi-orthogonal code and occurs by a loss of an orthogonality in a Code Division Multiple Access(CDMA) communication system using the orthogonal code and the quasi-orthogonal code is provided. CONSTITUTION: A CDMA type communication system comprises: a receiving apparatus for eliminating an interference from an orthogonal code channel to a quasi-orthogonal code channel; an estimating apparatus for estimating a channel by using a pilot signal for detecting a synchronization; a detecting apparatus for detecting the synchronization by using the estimating value of the channel; an estimating apparatus for estimating the interference from the orthogonal code channel to the quasi-orthogonal code channel; and an eliminating apparatus for eliminating the interference by the orthogonal code channel.
