What is justeen codes in communication system?
Justeen codes, also known as Jost codes, are a type of error-correcting code used in communication systems to enhance data transmission reliability. They are designed to detect and correct errors that may occur during the transmission of information over noisy channels. By using specific mathematical constructs, Justeen codes can efficiently encode data, allowing for recovery even when some bits are altered or lost. Their application is crucial in various digital communication systems, ensuring accurate data delivery.
Definition of Medio communication?
Madio communication refers to the means of delivering and receiving data or information to a large number of people. In telecommunication, these means are transmission and storage tools or channels for data storage and transmission.
What are logical channels between MS and BTS?
Logical channels between a Mobile Station (MS) and a Base Transceiver Station (BTS) are channels that facilitate the transmission of data and control information. They include dedicated channels, such as the Traffic Channel (TCH) for user data and the Signaling Channel (SCH) for control messages. Additionally, common channels like the Broadcast Control Channel (BCCH) and Random Access Channel (RACH) enable essential communication for network access and information dissemination. These channels are crucial for ensuring efficient and organized communication in mobile networks.
What is the computer network?
It is simply a network of computers connected together by different communication channels that allow sharing of data and information.
What is data transmission?
Data transmission is the transfer of data from point-to-point often represented as an electro-magnetic signal over a physical point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, and storage media. The term usually refers to digital communications (i.e. digital bit stream), but may include analog data transmission as well. Data transmission is a subset of the field of data communications, which also includes computer networking or computer communication applications and networking protocols, for example routing and switching.
What is convolution coding in communication?
Convolutional coding is an error-correcting technique used in digital communication systems to improve the reliability of data transmission over noisy channels. It involves encoding data streams into longer sequences by convolving the input data with a series of predefined polynomial functions, which generates redundant bits that help detect and correct errors at the receiver. The encoded data is typically represented as a sequence of bits, and the decoding process often employs algorithms like the Viterbi algorithm to retrieve the original message while minimizing errors. This method is particularly effective in scenarios where maintaining data integrity is critical, such as in satellite communications and mobile networks.
Data communication media?
Various media are used for data communication. Communication media refers to the means of delivering and receiving data or information. In telecommunication, these means are transmission and storage tools or channels for data storage and transmission.

What is FEC telex mode?
FEC telex mode refers to a communication protocol used in telex systems to ensure reliable message transmission. FEC stands for Forward Error Correction, a technique that adds redundancy to the transmitted data, allowing the receiver to detect and correct errors without needing a retransmission. This mode enhances the integrity of messages sent over potentially noisy channels, making it particularly useful in telecommunications and data transmission scenarios.
What is signals in data communication?
In data communication, signals refer to the variations in physical quantities that carry information over a medium. These signals can be analog or digital, with analog signals representing data as continuous waves and digital signals encoding data in discrete binary values. The transmission of these signals enables the exchange of information between devices over various channels, such as wired or wireless networks. Effective signal transmission is crucial for ensuring data integrity and communication reliability.
