DSB
DSB-SC信号的生成与解调
1) 用离散(DSP)的方法生成DSB信号
2) 载波频率为150KHz,音频为500Hz和2000Hz的混合音。
3) 加入高斯白噪声
(4) 语音信号
的传输。
改变抽样频率和量化台阶大小,观察重建信号以及量化噪声信号的波形;对于语音信号主观评价声音质量的变化。
-DSB-SC signal generation and demodulation 1) Discrete (DSP) methods to generate DSB signal 2) the carrier frequency to 150KHz, audio 500Hz and 2000Hz for the mixed tone. 3) by adding white Gaussian noise (4) transmission of voice signals. Change the sampling frequency and quantization step size, to observe the reconstruction of signal and quantization noise signal waveform for subjective evaluation of the speech signal changes in sound quality.

1、(1)32bit乘法的指令解释
(2)volume1的load.asm基础上实现一个
16bit数组的乘法累加的函数,并进行 -o2 / -o3 / 手工优化
2、c环境
C调用汇编函数,汇编函数调用c函数
addarr3(int * arr1, int * arr2, int * arr3, int * arr4, n)
//汇编函数,3个数组的对应位置相加,结果放在arr4[n]中,
汇编函数调用C的子函数,它把arr1和arr2相加放到arr3[n]中;
addarr2(int * arr1, int * arr2, int * arr3, n)-1, (1) 32bit multiplication instructions explained (2) the load.asm volume1 on the basis of a a 16bit multiplication cumulative array of functions, and-o2 /-o3/2 manual optimization, c environment compilation called C function, the compilation function call c function addarr3 (int* arr1. int* arr2, arr3 int*, int* arr4, n)// compilation function, 3 arrays corresponding location together, the results on arr4 [n], the compilation of the C function call function, arr1 put it together and put arr2 arr3 [n]; addarr2 (int* arr1, int* arr2, int* arr3, n)
