VHDL/FPGA/Verilog VHDL实现循环码编码
VHDL实现循环码编码,设计了三个单元。switch是一个开关,shifter是移位寄存器,encoder是主体。
通讯/手机编程 Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assum
Computes BER v EbNo curve for convolutional encoding / soft decision
Viterbi decoding scheme assuming BPSK.
Brute force Monte Carlo approach is unsatisfactory (takes too long)
to find the BER curve.
The computation uses a quasi-analytic (QA) technique that relies on the
estimation (approximate on ...

单片机开发 Library and command line program for Huffman encoding and decoding both files and chunks of memory.
Library and command line program for Huffman encoding and decoding both files and chunks of memory. The encoder is a 2 pass encoder. The first pass scans the data and builds the Huffman tree. The second pass encodes the data. The decoder is one pa
Linux/Unix编程 Linux环境下做的x264的全部源码
Linux环境下做的x264的全部源码,还有encoder哦!这个没有Windows下面的工程,但是很容易手工建立。虽然不是我写的,但确实是非常好的学习“x264”的资料

书籍 DRM023_3-Phase AC Designer Reference Manual
This reference design describes the design of a 3-phase AC induction
vector control drive with position encoder coupled to the motor shaft. It
is based on Motorola’s DSP56F805 dedicated motor control device.
AC induction motors, which contain a cage, are very popular in variable
speed drives. They ...
