It has always been a challenging task to implement a turbo decoder because it's typically the most compute-intensive and time-consuming part in a wireless communication system. This becomes especially obvious when realizing a turbo decoder through CPUs or GPUs. In this paper, we present a heterogeneous and highly reconfigurable parallel turbo decoder for LTE by employing a multi-core processor platform. A modified sliding-window algorithm is proposed to fully exploit the parallelism of turbodoi:10.1587/elex.14.20170768 fatcat:x2aqxwic3fejppmx4rykgvceti
