伪随机序列是人们经常使用的一种信号序列。例如,在线性预测语音合成中,当语音为清音时,激励信号就为伪随机序列。目前常用的伪随机序列产生器由M序列产生器或微处理器查表实现。本文介绍一种用TMS32010计算产生伪随机序列的方法。一、方法介绍在计算机模拟中,中们经常采用程序(A)去产生均匀分布伪随机数。从程序(A)我们可以看到,产生一个伪随机数只需作一次乘法和一次取小数运算即可。由于TMS32010乘法速度很,因此用TMS32010实现上述方法显然是非常方便的。当取变量YFL和u运算
Pseudo-random sequence is a signal sequence that people often use. For example, in linear predictive speech synthesis, when the speech is unvoiced, the excitation signal is a pseudo-random sequence. The commonly used pseudo-random sequence generator by M sequence generator or microprocessor look-up table to achieve. This article describes a method used to generate pseudo-random sequence generated by TMS32010. First, the method introduced In computer simulation, they often use the program (A) to produce a uniform distribution of pseudo-random number. From the program (A) we can see that to generate a pseudo-random number only need to make a multiplication and a decimal arithmetic. Because TMS32010 multiplication speed is very fast, so using TMS32010 to achieve the above method is obviously very convenient. When taking variables YFL and u operations
