the line-coded signal (the baseband signal) undergoes further pulse shaping (to reduce its frequency bandwidth) and then is modulated (to shift its frequency) to create an RF signal that can be sent through free space. the line-coded signal can be used to turn on and off a light source in free-space optical communication, most commonly used in ...
The Sri Lanka Media Training Institute (SLMTI) is an autonomous establishment under the Ministry of Mass Media and Information. [ 1 ] [ 2 ] It was founded in 1984; as the Sri Lankan Television Training Institute to train professionals in the field of television.
ESOFT was established in Kirilapone (which is a suburban area of Colombo, Sri Lanka), and initially offered training services for students that were preparing for the BCS (UK) Professional Examinations. [2] They subsequently moved to their present location in Bambalapitiya (Colombo) which is a hub for IT training in Sri Lanka [citation needed].
Random linear network coding [9] (RLNC) is a simple yet powerful encoding scheme, which in broadcast transmission schemes allows close to optimal throughput using a decentralized algorithm. Nodes transmit random linear combinations of the packets they receive, with coefficients chosen randomly, with a uniform distribution from a Galois field.
the mutual information, and the channel capacity of a noisy channel, including the promise of perfect loss-free communication given by the noisy-channel coding theorem; the practical result of the Shannon–Hartley law for the channel capacity of a Gaussian channel; and of course; the bit - a new way of seeing the most fundamental unit of ...
The Hardy Advanced Technological Institute [5] is located in Ampara, Sri Lanka. [6] Founded in 1956 by Prof. Allen Hardy as the Technical Training Institute with aid from the Colombo Plan, Food and Agriculture Organization (FAO) and the Asia Foundation, it was renamed as Hardy Senior Technical Institute (HSTI) in 1967.

Early disk drives used very simple encoding schemes, such as RLL (0,1) FM code, followed by RLL (1,3) MFM code, which were widely used in hard disk drives until the mid-1980s and are still used in digital optical discs such as CD, DVD, MD, Hi-MD and Blu-ray. Higher-density RLL (2,7) and RLL (1,7) codes became the de facto industry standard for ...
Two-binary, one-quaternary (2B1Q) is a line code used in the U interface of the Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) and the high-bit-rate digital subscriber line (HDSL). [1] 2B1Q is a four-level pulse-amplitude modulation (PAM-4) scheme without redundancy, mapping two bits (2B) into one quaternary symbol (1Q).
