Keywords:LDPCcode;weightedbitflippingalgorithm;high-speeddecoding 1引言 LDPC码具有逼近香农限的良好译码性能,在 近年来得到了广泛的关注,并且已经被纳入多种系 统标准中,比如Wi-Fi(IEEE802.11n) [1] 、10Gbit Ethernet(IEEE802.3an) [2] 、DVB-S2 ...
In this paper, we proposed high speed LDPC encoder architecture for DVB-S2 standard. In conventional algorithm, the processes of parity calculations are serial fashion. Therefore conventional algorithm need clocks of number of parity. The proposed LDPC encoding architecture is based on a parallel 360...
It provides LDPC, polar and turbo FEC solutions which enable optimal performance of communication systems and solves the challenges that would otherwise limit the speed of 5G, namely the error correction decoding that is required to overcome the effects of noise, interference and poor signal strength...
This software might be useful for others who want to use LDPC codes in their Matlab/Octave work, then run them in real time in C. With the (2064,512) code, the decoder runs at about 500 kbit/s on one core of my old laptop. I would also like to explore the use of these powerful...
