  Abstract

In this paper, M-ary Amplitude Phase Shift Keying (M-APSK) and Differential APSK (M-DAPSK) systems using channel coding are designed and evaluated. The channel codes considered in this paper are Low-Density Parity Check (LDPC) code and turbo code. LDPC and turbo codes are powerful error correcting codes that can achieve performance close to Shanon"s limit. As results of the simulation, in both 8-DAPSK and 16-DAPSK systems, turbo coding shows better BER performance with lower coding rate when the number of iterations of the channel decoder is 5. However, It is confirmed that the LDPC coding has better BER performance even though it has a higher code rate when the number of iterations of the channel decoder is 20 or 50. This tendency is similar in the APSK system. That is, when the reception processing time is sufficiently secured in the APSK and DAPSK systems, it can be confirmed that the use of the LDPC code is advantageous for higher efficiency transmission.
