16/64 point FFT

This is a FFT library function by using VHDL code. It can switch the length of FFT between 16 point and 64 point. It contains the butterfly, twiddle factor, ROM, RAM and so on. And it can successfully run on Quartus 2 or other software....

VHDL for 16 bit Time Domain Convolution

Convolution is a common operation in digital signal processing. In this project, I created a custom circuit implemented on the Nallatech board that exploits a significant amount of parallelism to improve performance compared to a microprocessor. Convolution takes as input a signal and a kernell The...

This is an exercise in designing combinational circuits that can perform binary-to-decimal number conversion and binary-coded-decimal (BCD) addition....

turbo coder

CHAPTER2LUT-LOG-BCJRARCHITECTUREThe energy consumption of conventionalLUT-Log-BCJR architectures cannot be significantly reduced by simply reducingtheir clock frequency and throughput. This motivates our novel architecture ofimplementing the basis ACS circuit in the system which is specifically desi...

OFDM Modulation and Demodulation

Cyclic prefix insertion is commonly used in orthogonal frequency division multiplexing (OFDM) systems as a way  to mitigate the effects of intersymbol-interference (ISI). It copies the end section of an inverse fast Fourier  transform (IFFT) packet to the beginning of an OFDM s...
