Abstract :
A new integration scheme for an adaptive array antenna and an MAI canceller is proposed. Computer simulations show it to have a better performance with less computation load than the conventional scheme. In addition, by using part of tentative decisions as pilot symbols virtually, further considerable performance improvement is attained especially in higher Eb/N0 region and in case of many users
