FIR滤波 FPGA
应用背景 FIR(fini te impulse response)滤波器是数字信号处理系统中最基本的元件，它可以在保证任意幅频特性的同时具有严格的线性相频特性，同时其单位冲激响应是有限的，没有输入到输出的反馈，系统稳定。因此，FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。关键技术在进入FIR滤波器前，首先要将信号通过A／D器件进行模数转换，使之成为8bit的数字信号，一般可用速度较高的逐次逼进式A／D转换器，不论采用乘累加方法还是分布式算法设计FIR滤波器，滤波器输出的数据都是一串序列，要使它能直观地反应出来，还需经过数模转换，因此由FPGA构成的FIR滤波器的输出须外接D／A模块。

在这个仿真模型，16
In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal
is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset
can be seen by varying the phase of down-sampling
operation.The signal transmitted is recovered
at the detector output.-In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal
