2. This algorithm has theoretical knowledge and Verilog Program
In digital signal processing , Complex multiplication has many applications , Including signal mixing ,FFT,IFFT. The calculation formula of complex multiplier is as follows :
Set the plural number
x = a + b i,
y = c + d i,
Then the result of multiplication of complex numbers is :
x * y = (a + b i)*(c + d i) = (ac - bd) + i (ad + bc) .
From this we can see that , A complex multiplier , Including four multipliers ( complete a*c,b*d,a*d as well as b*c), Three adders .
The implementation of multiplier , Refer to the previous course :
