The decoding algorithm used in RBDS.c is based on error trapping. The program emulates the operation of the encoder and decoder of a binary cyclic codes, using bitwise shifts and xor for modulo g(x) operations.

構(gòu)成及源代碼： 1 構(gòu)成：VB程序調(diào)用VC編寫的OCX，這樣做是為了方面大家自己做界面。 2 OCX的輸出函數(shù)：只有一個(gè)：void CQQDecoderCtrl::Decoder(LPCTSTR fileQQ, LPCTSTR filePwd) ，第一個(gè)參數(shù)是QQ的密碼文件，第二個(gè)參數(shù)是密碼字典。 3 源代碼：VB的源代碼不作介紹了，附件里面有。這里只說明一下VC的源代碼（附件里面也有）。

This a software runing on the matlab, it is used in the channel coding simulation. It include DVB-S2 LDPC, Covolution turbo, and block turbo code, You can choose which channel coding to run. it run the encoder and add white noise in the channel, then it run the decoder, and compute the error rate.

his packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (Matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder). You should run "Simulation.m" function that include all modules.

Spartan 3 Digilent Demo:This demo drives the perphrials on the Spartan 3 board. This drives a simple pattern to the VGA port, connects the switches to the LEDs, buttons to each anode of the seven segment decoder. The seven segment decoder has a simple counter running on it, and when SW0 is in the up position the seven segment decoder will display scan codes from the PS2 port. This demo how ever does not drive the RS-232 port or the memory. This is a simple design done entirely VHDL not microblaze.

This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources is used. Specific hardware bit-latching capabilities of the Timer_A3 module are used for real-time decoding of the IR data signal, independent and asynchronous to the CPU. CPU activity and power consumption are kept to an absolute minimum level. The Timer_A3 decoder implementation also allows other tasks to occur simultaneously if required. The solutions provided are written specifically for MSP430x11x(1) and MSP430x12x derivatives, but can be adapted to any other MSP430 incorporating Timer_A3. 電視遙控器設(shè)計(jì)基於MSP430

In recent years large scientific interest has been devoted to joint data decoding and parameter estimation techniques. In this paper, iterative turbo decoding joint to channel frequency and phase estimation is proposed. The phase and frequency estimator is embedded into the structure of the turbo decoder itself, taking into consideration both turbo interleaving and puncturing. Results show that the proposed technique outperforms conventional approaches both in terms of detection capabilities and implementation complexity.

G729編碼和解碼的Matlab源程序 調(diào)用方法： 1.需要編碼時(shí)，在 Matlab命令行下輸入"G729code(speech)"(請(qǐng)務(wù)必保證 speech是已經(jīng)存在在 Matlab工作區(qū)的一個(gè)行向量，其中是語音數(shù)據(jù))，然后你會(huì)在你的文件夾下看到一個(gè)"coding.bit"的文件。 2.需要解碼時(shí)，把"coding.bit"的文件復(fù)制到"G729 decoder"的目錄下，在Matlab命令行下輸入"G729decodermain"，然后你會(huì)在文件夾下看到"syn_speech.wav"，那就是重構(gòu)語音。 enjoy it!
