As a class of block codes. LDPC code with any desired code rate and code length is easily constructed. In this paper, we examined the performance of three high-rate (0.769,0.889,0.935) LDPC codes in image transmission. Simulation results show that LDPC codes are good coding schemes over fading channel in image communication with lower system complexity. The distorted images can be recovered by using the three high-rate LDPC codes at SNR 10 dB. 11.5 dB and. 14 dB respectively. These high-rate codes can achieve relatively higher bandwidth efficiency than that of the low-rate codes. Moreover we discovered that the code rate has more influence upon the performance than that of the code length. |
