چکیده
This paper describes a novel architecture for parallel turbo decoding used in Long Term Evolution (LTE) systems. The decoding scheme contains only one Quadratic Permutation Polynomial (QPP) interleaver, independently on the parallelization factor. Also, we propose an efficient implementation for the QPP interleaver. The arithmetic properties of the corresponding interleaver equations are exploited to perform the address computation in a recursive manner. The proposed decoding structure is evaluated in different radio environments and with several connection settings (modulation, data block length.)

Convolutional Turbo encoding is employed for channel coding in most modern communication standards. It has been shown to provide better bit error rate performance than convolutional encoding but this increase in performance comes at a considerable cost in implementation complexity to achieve required decoding throughput. Convolutional Turbo codes (CTC) are constructed by a parallel concatenatio...
