Untainted Puncturing for Irregular Low-Density Parity-Check Codes [PDF]

open access: yesIEEE Wireless Communications Letters, 2012
Puncturing is a well-known coding technique widely used for constructing rate-compatible codes. In this paper, we consider the problem of puncturing low-density parity-check codes and propose a new algorithm for intentional puncturing.

Rate-Compatible Puncturing of Low-Density Parity-Check Codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2004
In this correspondence, we consider puncturing of low-density parity-check (LDPC) codes for additive white Gaussian noise (AWGN) channels. We show that good puncturing patterns exist and that the puncturing can be performed in a rate-compatible fashion ...

Lumbar puncture

The Journal of Emergency Medicine, 1985
Lumbar puncture has been in widespread clinical use for nearly a century. It is used in emergency medicine primarily as a tool for the diagnosis of meningoencephalitis and subarachnoid hemorrhage. The development of computed tomography has changed the position that lumbar puncture has held in the diagnostic sequence of a number of clinical entities ...

LUMBAR PUNCTURE

Journal of the American Medical Association, 1942
The use of lumbar puncture in the investigation of lesions of the central nervous system has become so standardized that it is almost as much of a routine procedure as the systematic study of the reflexes. The saying that "familiarity breeds contempt" may be aptly applied to this procedure, for one seldom considers that there is any real danger ...

Puncture Wounds

Pediatrics In Review, 1999
Puncture wounds are common in children, and most are uncomplicated. For children who have a delayed presentation or signs of infection, consider the possibility of a retained foreign body. The diagnosis of P aeruginosa osteochondritis should be considered in any child who exhibits persistent signs and symptoms after puncture wounds; timely use of ...
