Abstract
The present invention provide a space time block codes (STBC) scheme, where a received signal is filtered by using a minimum mean square error (MMSE) filter, and where channel symbols are individually decoded and converted into bit information, so that an mean square error (MSE) can be minimized by using a linear superposition form applicable to the non quasi-static channel environment as well as a quasi-static channel environment. The present invention provides an STBC scheme using a MMSE filter obtained in a real linear representation method, so that transmitted data can be recovered without loss thereof even in a case where a speed of a mobile station is high.
