I am designing a channel encoder (bch/RS/Turbo) + Modulator based digital communication system in simulink. My blocks in the design are 1) Ber. B. Gen/Ran Int Gen 2) bch (15,7) or RS (255,223) Encoder & decoder 3) QPSK/M-ary PSK Mod & De Mod 4) AWGN Channel the problem i am facing is the input to the modulator/demodulator should (...)
Can anyone give the complete matlab code for bch coding and decoding? Though the direct function is available in MATLAB, I want to know how did they design the code.
hi.... i am doing bch decoder implementation in FPGA. plz send some informations and related documented to Hardware implementation of bch decoder ...
Hi..... I am Implementing bch decoder In FPGA... so in syndrome calculation for bch decoder .... we need to multiply the input data with ALPHA .... so please any one can send the ALPHA values ....
How to implement bch decoder for 7,4 code..?.. I want to decode (7,4) bch code and have successfully obtained the syndrome,how to implement Chien search circuit for this decoder..?(can correct 1 bit..)
3GPP message decoder is a very simple but powerful tool to decode GSM, UMTS, LTE, IP messages. The decoder supports: GSM GAN TCP GAN UDP GSM CCCH GSM SACCH LLC NAS SNDCP SNDCPXID UMTS NAS RRC BCCH.bch RRC BCCH.FACH RRC DL.CCCH RRC DL.DCCH RRC DL.SHCCH RRC (...)
For a project I need a program written in C or C++ which can encode and decode(bch coding) Encoding means when we input the data bits the program should output the coded word Decoding in the sense when we input the received code word the decoder should output the original data bits. If there is any error decoder should be able to correct them.
Hi, I want to implement parallel bch decoder.First step of decoding is syndrome computation.I do not know how go generate parallel 2t syndrome for bch decoder. Can any one guide me ? or Can anyone give me some material for that ? Thanks in advance.
Hello everyone, I want to know how can I see the BER with Eb/No. when one is using bch coder and decoder together with awgn channel,rayleigh fading channel and bpsk modulator and demodulator in matlab simulink. Can I get graph for it,if yes, then how? However I have seen the fading effect on new version of matlab. Can I see fading effect and BER on

Hai all... butuh bantuan nih.. sy lagi ngedesain blok pengkodean untuk standar DVBs2 menggunalakn Matlab,,yg menggunakan LDPC encoder+interleaver+bch encoder (diblok transmitter)..sedangkan diblok receiver kebalikannya (bch decoder+deinterleaver+LDPC decoder) masalahnya keluaran dari bch (...)
Does anybody has the verilog source code for bch decoder? i am studing the bch algorithm in my project, i want to get some code for reference, thanks! my email
Please I want to know what the "Key Equation" is Solving this equation is an importan step in decoding bch Codes like Reed-Solomon At the decoder ,after calculating the Syndrome, the next blook is "KES Block" (Key Equation Solver Block) please help me thanks
hello every body i need bch decoder using berlekamp masseyAlgorithm in c++ kindly email me at
hi bchenc(gf(msg),n,k) is bch encoder command and bchdec(gf(msg),n,k) is bch decoder. refer to MATLAB Help.
Hello, I need an example of a Basic bch error control enc/dec in matlab ... umm anybody can help ? i need it for at least n= 31 , k = 21 .... thanks in advance
There are the two implementations uploaded. Anyway I did not manage to run the RS one. Therefore, I decide to use bch. I'm not expert in ECC, but my tests in Matlab showed that I can encode 1 bit more using bch (valid for my case only). In Matlab the RS is slower than bch.
Hi, can anyone provide some books, tutorials or datasheets of IP cores for bch encoder/decoder ? Thanks in advance.
