Parallel Turbo decoding encounters conflicts during parallel data accesses because of the sequential data interleaving, and the conflicts lead to a serious decrease of throughput. Traditional conflict-free memory mapping schemes often require a huge cost of hardware, such as the area of memory, which is also a bottleneck in practical implementations. In(More)
In 5G communications, to meet the higher throughput requirement of Turbo decoding, Quadratic Permutation Polynomial (QPP) interleaver is adopted for contention-free parallel memory access. However, with the intrinsic attribute of QPP interleaver, the contention-free memory access is achieved only when the codeword length is divisible by the degree of(More)
Forward Error Correction (FEC) consumes excessive computation in a Software Defined Radio (SDR) system. In this work, a high-throughput flexible FEC processor is proposed for the decoding acceleration. The FEC processor enables Turbo/QC-LDPC/Convolutional Code decoding with software-hardware co-reconfigurability. A multi-algorithm unified trellis processing(More)
Nowadays multi-standard wireless baseband, Convolutional Code (CC), Turbo code and LDPC code are widely applied and need to be integrated within one FEC module. Since memory occupies half or even more area of the decoder, memory sharing techniques for area saving purpose is valuable to consider. In this work, several memory merging techniques are proposed.(More)
