In this paper, we study the performance benefits of turbo coded HSDPA system. This paper provide an overview of high speed data packet access (HSDPA) and focus on the business values that such a highly-efficient access technology would bring to wireless operators, including higher capacity and newer services. In this paper each frame is encoded using a turbo code and channel coding is done by turbo codes is the best method for transmitting information with fewer errors and lower signal power. Turbo coding includes two main modules in it, one being turbo encoder made up of recursive systematic code encoders and second turbo decoder where Log Map algorithm is implemented. HSDPA increases the downlink data rate within a cell to a theoretical maximum of 14Mbps, with 2Mbps on the uplink. The changes that HSDPA enables include better quality and more reliable, more robust data services. In other words, while realistic data rates may only be a few Mbps, the actual quality and number of users achieved will improve significantly.
