16-QAM is a type of Quadrature Modulation (QAM) in which a carrier wave of a fixed frequency can exist in one of sixteen different states. This can be represented in a constellation diagram (Figure 1) where each state is a symbol that contains one of 16 different amplitude and phase leve...

需要注意的是,这里的HM 4/16 QAM并不是传统意义上的16个符号的16-QAM调制,而是通过两个QPSK信号的叠加来模拟一种简化的分层调制效果。真正的16-QAM会使用16个不同的复数符号来表示4个比特的数据。然而,在本研究中,我们关注的是分层调制的概念,而不是16-QAM的完整实现。 2.3 传输与接收 在传输侧,我们将叠加...

WCDMA下载时,采用16QAM和QPSK有什么区别?两者是指定的还是自动分配的?参数设置?请大侠们帮帮忙! 在对基站进行HSDPA下载测试时,发现有时采用的是16QAM Modulation,这时候下载速率很好,能达到2.5M以上,有时却只采用QPSK Modulation,下载速率最高只有1.5M,此时的RSCP和EC/NO都较好,请大侠们帮帮忙?
