Polar Codes with exponentially small error at finite block length [PDF]

open access: yes, 2018
We show that the entire class of polar codes (up to a natural necessary condition) converge to capacity at block lengths polynomial in the gap to capacity, while simultaneously achieving failure probabilities that are exponentially small in the block ...

A New Class of Braided Block Codes Constructed by Convolutional Interleavers

open access: yesMathematics
Parallel Concatenated Block (PCB) codes are conventionally represented as high-rate codes with low error correcting capability. To form a reliable and outstanding code, this paper presents a modification on the structure of PCB codes, which is ...

Two new best [27,10,9 ] codes

open access: yesCommunications, 2000
This paper presents two new [27,10,9] binary linear block codes which reach the upper bound in [1] for best known codes. They have different spectra as the known [27,10,9] codes constructed by Piret [2], Farkaš and Juling [5].

Convolutional and tail-biting quantum error-correcting codes

open access: yes, 2005
Rate-(n-2)/n unrestricted and CSS-type quantum convolutional codes with up to 4096 states and minimum distances up to 10 are constructed as stabilizer codes from classical self-orthogonal rate-1/n F_4-linear and binary linear convolutional codes ...

Unified OSTBC-based communication scheme for cooperative space vehicles

open access: yesThe Journal of Engineering, 2019
In many spatial cooperative vehicle networks, omni-directional communication is preferred due to its flexibility for networking. In the recent studies, space time code was shown to be an effective approach for improving the performance of the omni ...

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

Two Faces of NOTCH1 in Childhood Lymphoblastic T‐Cell Neoplasia: Prognostic Divergence of Mutational and Structural Aberrations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...

Evaluasi Kompleksitas Pendekodean MAP pada Kode BCH Berdasarkan Trellis Terbagi

open access: yesJurnal Nasional Teknik Elektro dan Teknologi Informasi, 2017
Soft decoding of block codes can be done by representing the block code into the trellis. One method of soft decoding commonly used is the maximum a posteriori probability (MAP).

Repairable Block Failure Resilient Codes

open access: yes, 2014
In large scale distributed storage systems (DSS) deployed in cloud computing, correlated failures resulting in simultaneous failure (or, unavailability) of blocks of nodes are common.
