Yuling Zhan, Dongfeng Yuan, Haigang Zhang, Haixia Zhang · 2004
In this paper, we combine the adaptive modulation and coding (AMC) with LDPC (low-density parity-check) codes and apply it to image transmission under Rayleigh fading channels. The transmitter adjusts the modulation mode according to the channel state information. Through computer simulation, we get the performance of our adaptive LDPC scheme in image transmission under certain demand of BER, and we also study the impacts of channel estimation error. We can see that in image transmission, our adaptive LDPC scheme can provide an acceptable image quality, meanwhile a higher spectral efficiency.
