DSPcorrelation
- 相关算法的应用很广,例如噪声中信号的检测,一个信号经过一段延迟后自身的相似性,信号中隐含周期性的检测,信号相关性的检验,信号时延长度的测量,滤除确定性信号中的随机干扰信号等等。相关函数还是描述随机信号的重要统计量。 利用CCS5000的集成开发平台,通过C语言对一正弦信号和一余弦信号进行了相关算法设计、编程和分析,然后将其置于CCS集成开发环境下,编译、调试、运行.-correlation algorithm used widely, such as noise signal detecti

Quartus
- Quartus程序是滤波器+功率检测+相关计算+TDD时隙切换,从滤波输出的过采样信号中随机指定输出其中的一路信号输出用来做功率检测和相关计算,相关计算完全采用串行计算比较的方式得到最大值,然后根据这个最大值的位置推算出上、下行时隙的切换点位置。-Filter+ Quartus program is related to computing power detection++ TDD time slot switch, from the filtered output signal over a
PN4
- 语言:VHDL 功能:该PN4序列的特点为将一个4位序列的前两位取异或,再让序列左移一位,用异或的结果作为序列的最后一位。序列周期是15,即15位伪随机序列。其中包括序列的产生模块和检测模块。对于误码检测,首先捕获相位。然后,规定测试的码的总个数,统计这些码中有多少个不能满足PN序列特点的,用计数器统计个数。如果发现误码过多,可能是相位失调,重新捕获相位,再进行误码检测。 仿真工具:modelsim 综合工具:quartus -Language: VHDL function:
