Description: QPSK modulation system with recover loops-This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.

Description: 我对一个输入调制信号：采样率FS=1200K，中心频率F0=300K，带宽300K。输入信号为一个[样点数,2]的矩阵,即I,Q两路.
进行频谱搬移，分为I，Q分量两路进行矢量乘法，NCO的设置为FC=300K，t=样点数乘以1/FS，
乘完以后我的频谱上显示竟然信号带宽增加了300K，但是中心频率没有改变，请问各位朋友是哪儿出了问题？谢谢您的阅读和意见-Digital Down Converter for matlab realized, certain design specifications that can be used to know VHDL Programming
