摘要
联合检测技术(JD)是TD-SCDMA系统的关键技术之一。介绍了JD算法的基本原理,研究了在不同信噪比(SNR)时,用不同码道数在未编码传输中对JD解码的影响,计算了数据在不同码道数和不同信噪比情况下各个码道中symble的功率。仿真结果表明:码道数越小,JD解码性能越好。
Joint detection(JD) is one of the key technologies of TD-SCDMA system.This paper introduces the basic principle of JD,and the impact on JD with different number of PhCHs within uncoded data in different SNR,And the Energe of symbles in each PhCH in different number of PhCHs and different SNR are calculated.The of simulation results show that the fewer PhCHs are,the better performance JD is.
