Modern communication systems must cope with varying channel conditions and differing throughput constraints. Polar codes despite being the first error-correcting codes with an explicit construction to achieve the symmetric capacity of memoryless channels are not currently employed against other older coding protocols such as low-density parity check (LDPC) codes as their performance at short/moderate lengths has been inferior and their decoding algorithm is serial leading to low decoding throughput. Accordingly techniques to address these issues are identified and disclosed including decoders that decode constituent codes without recursion and/or recognize classes of constituent directly decodable codes thereby increasing the decoder throughput. Flexible encoders and decoders supporting polar codes of any length up to a design maximum allow adaptive polar code systems responsive to communication link characteristics, performance, etc. whilst maximizing throughput. Further, designers are provided flexibility in implementing either hardware or software implementations.

A system and method of relay code design and factor graph decoding using a forward and a backward decoding scheme. The backward decoding scheme exploits the idea of the analytical decode-and-forward coding protocol and hence has good performance when the relay node is located relatively close to the source node. The forward decoding scheme exploits the idea of the analytical estimate-and-forward protocol and hence has good performance when the relay node is located relatively far from the source node. The optimal decoding factor graph is first broken into partial factor graphs and then solved iteratively using either the forward or backward decoding schemes.

The invention provides a method for transmitting a large data flow through a two-dimension code. The method achieves a bidirectional handshake process between a data analysis end and a collecting end through a two-dimension bar code protocol code.

This paper presents a methodology for designing System-On-Chip interconnection architectures providing a high level of protection from crosstalk effects. An event driven simulator enriched with fault injection capabilities is exploited to evaluate the dependability level of the system being designed. The simulation environment supports several bus coding protocols and thus designers can easily evaluate different design alternatives. To enhance the dependability level of the interconnection architecture, we propose a distributed bus guardian scheme, where dedicated hardware modules monitor the integrity of the information transmitted over the bus and provide error correction mechanisms.

Device and method for improved diagnosis and treatment of patients. Detailed coding protocols are instantly assigned to diagnoses and treatment plans created by clinicians based upon initial patient encounter. Past patient records (EHR) can be instantly searched using the assigned codes during the patient encounter, thereby allowing the clinician to make a more complete diagnosis and plan of treatment. The search of past patient records utilizes the assigned codes as a search index thereby filtering out unrelated-non relevant patient medical history. Clinician notations of symptoms and possible diagnosis can be utilized for an expanded correlation to codes of medical code protocols relevant to treatment or tests. This expanded listing of codes can be displayed to the clinician during the patient encounter for evaluation in determining a diagnosis. Correlated medical codes can be disclosed with calculated or past recorded reimbursement information.
