碩士 === 國立臺北科技大學 === 電子電腦與通訊產業研發碩士專班 === 95 === In this thesis, we investigate the performance evaluation of frequency hopping/MFSK system with soft-decision decoded error correction coding. The purpose of simulation is find out the best error correction codes among three error correction codes to improve the performance of no MAI of system. The error correction codes are considered in this thesis include convolutional codes, turbo codes, and Reed-Solomon codes. We proposed several soft-decision decoded methods for convolutional codes and turbo codes. Broadband Rayleigh fading channel and AWGN are considered. Finally, simulation results show that turbo codes with bit-interleaving(TC-BI) using maximum likelihood function has best performance among three error correction codes for no MAI of FHSS system.
