1,2,3,4,6-Pentakis[-O-(3,4,5-trihydroxybenzoyl)]-α,β-D-glucopyranose (PGG) 12 has been reported for its antioxidant activities, where the free OH groups in PGG seem to be critical for activities. To explore PGG-based compounds as chemotherapeutic agents and to analyze the contribution of specific OH groups in PGG for anti-cancer activities, we designed and synthesized a series of 27 benzoic and cinnamic...
Low density parity check code (LDPC) has constructed a flexible, low decoding complexity and performance close to Shannon limit benefits. This paper introduces the LDPC codes and bit-interleaved coded modulation with iterative decoding (BICM-ID) scheme, given its log-likelihood ratio belief propagation (LLR-BP) decoding algorithm. Achieved with LDPC codes as component codes in BICM-ID scheme is applied...
In MIMO communication system the conventional Turbo-BLAST receiver using Gray mapping converges slow. For this reason, an improved Turbo-BLAST scheme with Anti-Gray mapping is proposed in this paper. Research has shown that the iterative receiver using new scheme outperforms the convention alone and obtains a faster convergence rate. Also, an improved receiver based on soft interference cancellation...
In MIMO communication system, Turbo-BLAST based on random layered space-time coding and combination of iterative detection and decoding gains a high performance at the cost of computational complexity. The conventional iterative receiver based on soft interference cancellation still suffers a high complexity. For this reason, an improved low complexity soft detection algorithm is presented: By using...
In multiuser space-time coding system the research already made is almost focused on STTC and STBC scheme. For this reason, a multiuser space-time coding system combined with Turbo-BLAST scheme is investigated. Iterative processing has been shown to be very effective in multiuser space-time coding systems, where each user employs channel coding and iterations are performed between the soft-output...
