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.
