The calculation of LTE code rate is done based on MCS, PRBs and OFDM symbols per slot . The LTE code rate calculator outputs code rate. It takes into account percent of REs used in control channel operation. The PRBs stands for Physical Resource Blocks allocated to the UE by eNB.
Read moreWhy are different modulation and coding schemes used?
The different EDGE modulation coding schemes are used as required to provide the optimum balance between high data rate and low error rate . As signal levels fall and noise levels rise, the higher levels of error correction are needed to maintain the integrity of the link.
Read moreHow does modulation code scheme determine data rates?
Industrial Wireless Tutorials: Modulation and coding schemes (MCS) are used to determine the data rate of a wireless connection using high-throughput orthogonal frequency division multiplexing (HT-OFDM) .19 Ara 2014
Read moreWhat is modulation in LTE?
Modulation is the process of varying the properties of a carrier signal such as frequency, phase and amplitude with a modulating signal that contains the actual information to be transmitted . A modulator does the modulation of a signal and a demodulator does exactly the reverse of modulation.
Read moreWhat is modulation and coding scheme?
MCS (Modulation and Coding Scheme) defines how many useful bits can be transmitted per Resource Element (RE) . MCS depends on radio link quality. The better quality the higher MCS and the more useful data can be transmitted.

From Rel 12 , 3GPP defines (support) 256 QAM in Downlink.
Read moreWhat QAM 256?
Just what is QAM-256? It refers to Quadrature Amplitude Modulation , which is the means by which a carrier signal, such as an LTE waveform, transmits data and information. Ideally, a waveform/symbol carries as much data as possible in order to achieve higher data rates and increase spectral efficiency.
