| Abstract: | According to the principle of the RS code and encode, as well as the actual compressing effect of high-resolution remote sensing satellites, a scheme using RS(255,243) and RS(34,26) is proposed to satisfy the requirement of high-resolution remote sensing satellite data transmission. The emulation experiments show that the method is effective for the data transmission between satellite and the earth under interference condition, and it can prevent and reduce the error diffusion. |
