FPGASquare-RootRaised-CosineFilter
- 数字通信系统中, 基带信号的频谱一般较宽, 因此 传递前需对信号进行成形处理, 以改善其频谱特性,使 得在消除码间干扰与达到最佳检测接收的前提下,提高信道的频带利用率。目前,数字系统中常使用的波形成形滤波器有平方根升余弦滤波器、 高斯滤波器等。设计方法有卷积法或查表法, 其中: 卷积法的实现,需要消耗大量的乘法器与加法器,以构成具有一定延时的流水线结构。为降低硬件消耗,文献提出了一种分-FPGA Implementation of Square Root Raised Cosine Pu

BPSK
- 用于BPSK调制的自行设计,说明如下: 1.matlab.txt中的程序是matlab平台下的.mat格式。目的是输出一个64*4的矩阵,矩阵的每个元素都为0~255间的整数。矩阵每行的四个数是一个码元的四个抽样点的量化值。但由于当前码元通过升余弦滤波系统时,受到前后共6个码元的共同影响,所以是由6个码元共同决定。这6个码元是随机的,可能是0也可能是1(双极性时可能是-1也可能是+1),故6个码元共2^6=64种情况,所以产生的矩阵是64*4。最后逐行输出这256个数。 2.
