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.

说明：  采用多相滤波结构，可利用多个阶数较低的滤波来实现原本阶数较高的滤波，而且每个分支滤波器处理的数据速率仅为原数据速率的I/D，这为工程上高速率实时信号处理提供了实现途径。(By using polyphase filter structure, the original higher order filtering can be achieved by using multiple lower order filters, and the data rate processed by each branch filter is only I/D of the original data rate, which provides a way to realize high-speed real-time signal processing in engineering.)
