Abstract
Turbo codes are part of the standardization for the 3G wireless communication system. They have been chosen for their error correcting ability to approach the Shannon limit. In a standard turbo coding system, all bits are transmitted with equal energy. This strategy does not guarantee optimum allocation. UPA ( unequal power allocation) been adopted to optimize the power allocation for each bit stream. Using new modified technique for UPA, the performance of turbo codes is studied.
