In less than a year or two, third generation ( 3G) wireless communication systems will be replacing the currently existing second generation (2G) wireless systems and be used worldwide. The 3G systems will have a higher data transfer capacity, which allows for simultaneous data, voice, and video transfer (e.g., multimedia applications) while most of 2G systems only allow for low-rate data and voice transfer. The wireless communications industry has set standards for 3G, which detail various operations of the technology. It should be noted that the 3G standards outline only the different operations and not the processes for the production of these operations. The research presented addresses a method of production of the interleaver operation for randomization of burst errors. In this paper, the details of the interleaver are described and a novel method to implement the interleaving operation in a 3G system, called Universal Mobile Telecommunication Systems (UMTS) is presented. The implementation was aided by a sophisticated tool from Cadence, "Signal Processing Workstation" (SPW), which was used in both the design and testing of the interleaver. Of the two interleavers in UTMS standards, the first interleaver is the focus this research. However, this research would be applicable to the second interleaver.
