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.

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

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.

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.
