VHDL/FPGA/Verilog 16点FFT VHDL源程序
16点FFT VHDL源程序，The xFFT16 fast Fourier transform (FFT) Core computes a 16-point complex FFT. The input data
is a vector of 16 complex values represented as 16-bit 2’s complement numbers – 16-bits for
each of the real and imaginary component of a datum.

The frequency domain plays an important role in image
processing to smooth, enhance, and detect edges of images. Although
image data typically does not include imaginary values, the fast Fourier
transform (FFT) has been used for obtaining spectra. In this paper,
the fast Hartley transform (FHT) is u ...

This is a superheterodyne reciever simulation, created in MATLAB - Simulink. The purpose is to study the effect of perturbations on the imaginary frequence and on the intermmediate frequence, in the context of incoherent demodulation.
书籍 Digital Processing Optical Transmission
Optical communication technology has been extensively developed over the
last 50 years, since the proposed idea by Kao and Hockham [1]. However, only
during the last 15 years have the concepts of communication foundation, that
is, the modulation and demodulation techniques, been applied. This is pos ...
