摘要：Spread Spectrum technology can be considered as one of the most important communication technologies. Its basic idea is depending on enlarging the modulated signal Bandwidth throughout a second modulation. For the hybrid spread spectrum, most of the researches and applications focused on the Direct Sequence/Frequency Hopping Spread Spectrum, on the other hand a few researches deal the Direct Sequence/Frequency Hopping/Time Hopping hybrid spread spectrum systems. In this study, the performance of a coded Direct Sequence/Fast Frequency Hopping/Time Hopping system is analyzed and evaluated under the additive white Gaussian noise and frequency selective fading channel. The results show that the presented system provides a great performance enhancement due to its multi-spread spectrum techniques.
