The code rate of the octet oriented Reed Solomon block code denoted RS(204,188) is 188/204, meaning that 204 − 188 = 16 redundant octets (or bytes) are added to each block of 188 octets of useful information.
These codes achieve rate-1/2 and rate-3/4 respectively. These two matrices give examples of why codes for more than two antennas must sacrifice rate — it is the only way to achieve orthogonality. One particular problem with C 3 , 3 / 4 {\displaystyle C_{3,3/4}} is that it has uneven power among the symbols it transmits.
Scheduled services from the Chilean mainland started in 1967 with a monthly Douglas DC-6B propliner flight operated by LAN-Chile that took nine hours, [6] using a runway extended and paved for the use as a U.S. base. [7] In 1970, services were upgraded with weekly Boeing 707-320 nonstop jet service to Santiago, Chile and Faa'a International Airport (PPT) in Papeete, Tahiti.
The parity bit may be used within another constituent code. In an example using the DVB-S2 rate 2/3 code the encoded block size is 64800 symbols (N=64800) with 43200 data bits (K=43200) and 21600 parity bits (M=21600). Each constituent code (check node) encodes 16 data bits except for the first parity bit which encodes 8 data bits.

Alexei Kitaev's topological quantum codes, introduced in 1997 as the toric code, and the more general idea of a topological quantum computer are the basis for various code types. [ 16 ] Todd Brun , Igor Devetak , and Min-Hsiu Hsieh also constructed the entanglement-assisted stabilizer formalism as an extension of the standard stabilizer ...
A cryptographic key is called static if it is intended for use for a relatively long period of time and is typically intended for use in many instances of a cryptographic key establishment scheme. Contrast with an ephemeral key .
The group of islands ranges from 74° to 81° north latitude, and from 10° to 35° east longitude. [2] The Svalbard Treaty of 1920 recognizes Norwegian sovereignty, [ 3 ] and the 1925 Svalbard Act established administration by the appointed Governor of Svalbard . [ 4 ]
