Abstract
Low-pulse position modulation(L-PPM) modulation technique is widely used in atmospheric laser communication. In order to correspond to L-PPM modulation technique better and improve correction ability, channel coding employs error correcting code over finite field GF(q). After discussing RS encoding and decoding algorithms over GF(17), and studying the RS(16，10) encoding and decoding algorithms and its realization process, results show that RS(16,10) code over GF(17) can correct 2-bit random errors after channel interference when transmitter employs 16-PPM modulation mode.
