We consider a two-user non-orthogonal-multiple-access (NOMA) communication channel with an iterative multi-user receiver. It is known that NOMA provides performance gains over conventional orthogonal-multiple-access, but it comes at the cost of increased decoder complexity. Moreover, the decoder complexity varies with fraction of duration in which the users' transmissions overlap using NOMA. For this...
This work presents the VLSI hardware implementation of a novel Belief Propagation (BP) algorithm introduced in [G. Montorsi, “Analog digital belief propagation,” IEEE Commun. Lett., vol. 16, no. 7, pp. 1106–1109, 2012] and named as Analog Digital Belief Propagation (ADBP). The ADBP algorithm works on factor graphs over linear models and uses messages in the form of Gaussian like probability distributions...
This paper presents a highly parallel turbo decoding architecture for 3GPP LTE standard. High throughput is achieved by increasing the decoder parallelism and reducing window sizes. A batcher-sorting-based permutation network is presented which is able to support multi-standard applications. The proposed solution supports all codes specified by 3GPP LTE standard. High coding efficiency is achieved...
