Abstract

This paper investigates the performance of a coded quaternary Gaussian minimum shift keying (GMSK) signal with the low density parity check (LDPC) code. Performance simulation results for a frequency division multiple access (FDMA) communication system employing the LDPC-coded quaternary GMSK signal and an LDPC-coded QPSK signal are presented for a wide range of adjacent channel interference levels. It is shown that the LDPC-coded quaternary GMSK signal can have significant performance advantage over the LDPC-coded QPSK signal in an FDMA system with severe adjacent channel interference.

四元GMSK通信系统的编码性能

研究了用低密度奇偶校验码(LDPC)编码的四元高斯最小移位键控(GMSK)信号的性能。给出了采用ldpc编码的四元GMSK信号和ldpc编码的QPSK信号的频分多址(FDMA)通信系统在大范围相邻信道干扰水平下的性能仿真结果。结果表明，在具有严重相邻信道干扰的FDMA系统中，ldpc编码的四元GMSK信号比ldpc编码的QPSK信号具有显著的性能优势。
