What is channel coding rate?
The channel-coding rate is defined as which can be interpreted as the number of information bits per coded channel symbol. Assuming lossless transmission of these equiprobable binary words, the OPTA inequality reads: (2.23)
What is channel coding?
Channel coding is a process of detecting and correcting bit errors in digital communication systems. It is also known as forward error control coding (FECC). Channel coding is performed both at the transmitter and at the receiver.
What is the difference between source encoding and channel coding?
The goal of source coding is to represent a source with the lowest possible rate to achieve a particular distortion, or with the lowest possible distortion at a given rate. Channel coding adds redundancy to quantized source information to recover channel errors.
What is channel coding in LTE?
The LTE-Advanced channel coding is composed by five generic procedures: CRC calculation, code block segmentation and CRC attachment, channel coding, rate matching and code block concatenation. The aggregation of these procedures creates the great majority of the downlink and uplink transport channels.
