Minimum BER Receiver Filters with Block Memory for Uplink DS-CDMA Systems
EURASIP Journal on Wireless Communications and Networking, 2008 The problem of synchronous multiuser receiver design in the case of direct-sequence single-antenna code division multiple access (DS-CDMA) uplink networks is studied over frequency selective fading channels.

LDPC Codes with Local and Global Decoding
, 2019 This paper presents a theoretical study of a new type of LDPC codes motivated by practical storage applications. LDPCL codes (suffix L represents locality) are LDPC codes that can be decoded either as usual over the full code block, or locally when a ...

Turbo code design for short blocks [PDF]
2016 8th Advanced Satellite Multimedia Systems Conference and the 14th Signal Processing for Space Communications Workshop (ASMS/SPSC), 2016 This work considers the design of short parallel turbo codes (PTCs) with block lengths in the order of (a few) hundred code bits. In particular we aim at designing codes with large minimum distance. To this end a structured approach is presented to find suitable component code configurations, as well as interleavers.

Transcriptome‐wide analysis of circRNA and RBP profiles and their molecular relevance for GBM
Molecular Oncology, EarlyView.CircRNAs are differentially expressed in glioblastoma primary tumors and might serve as therapeutic targets and diagnostic markers. The investigation of circRNA and RNA‐binding proteins (RBPs) interactions shows that distinct RBPs play a role in circRNA biogenesis and function.

Molecular Oncology, EarlyView.Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.

Alamouti code based on block repetition in FBMC/OQAM systems
Digital Communications and Networks, 2022 In this paper, we address the Alamouti code in Filter-Bank Multicarrier with Offset Quadrature Amplitude Modulation (FBMC/OQAM) and propose a novel block-wise Alamouti code, in which a repeated block is designed to eliminate the imaginary interference ...

Code diversity in multiple antenna wireless communication
, 2008 The standard approach to the design of individual space-time codes is based on optimizing diversity and coding gains. This geometric approach leads to remarkable examples, such as perfect space-time block codes, for which the complexity of Maximum ...
