摘要
介绍了接近满码道工作时不能满足系统性能要求的联合检测技术,研究了能有效解决信噪比恶化问题、大大提高系统性能的多步联合检测技术;提出了改进的并行多步联合检测算法,减小了系统时延;并给出了SCDMA系统中的实现方案。
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.
