Abstract

Turbo Code is one of the most useful and powerful channel coding technique. It is adopted in radio transmission of IMT-2000, both CDMA2000 and W-CDMA system. The performance of this code depends on many parameters such as encoder memory size, free distance of codewords, interleaver size, number of decoding iteration, and so on. This paper describes a Multi-Stage Interleaver which is used in Turbo Codes for W-CDMA channel coding. We compare the performance of a Multi-Stage Interleaver with that of Mother Interleaver. The simulation results show that Multi-Stage Interleaver performs better than Mother Interleaver in bit error rate from $10^{-3}$ to $10^{-6}$.
