Recently, frequency-hopping code-division multiple-access (FH-CDMA) systems have been widely studied and known to be effective means of communications in combating multipath fading because of their inherent frequency diversity. With the explosive growth of wireless communication techniques, it is expected to be a flexible support of multimedia services (e.g., data, voice, image, and video) in the future wireless communication systems. Therefore, it is very important to design flexible wireless communication systems which can support a variety of data rates and quality-of services (QoS) requirements for these multimedia services, instead of the conventional communication systems which only can support the single media transmissions. In this thesis, we discuss the relationship between modulation codes and frequency hopping (FH) patterns in details. We integrate both codes to increase the number of simultaneous users and reduce the complexity of systems. The newly proposed system offers more flexibility for the design of systems to meet different system requirements.
