Coding rate in lte
WebTurbo codes are used in 3G / 4G mobile communications (e.g., in UMTS and LTE) and in ( deep space) satellite communications as well as other applications where designers seek to achieve reliable information transfer over bandwidth- or latency-constrained communication links in the presence of data-corrupting noise. WebCoding rate of 1 indicates no redundancy Physical Layer coding rate as a function of channel condition and modulation scheme Courtesy : LTE in Bullets QPSK and a Low coding rate are associated with poor channel conditions. Link adaption allocates larger transport block sizes as the channel conditions improve ,
