| Abstract: | Joint detection is introduced, which can not reach the need of system performance when system loads is close to the spread factor. MSJD is put forth to overcome the problem, and a improved parallel MSJD is presented to reduce system time delay, and then a practical scheme for MSJD in SCDMA is proposed. |
