significantly.

Analysis methods of increasing MSDS productivity.
MCS represents a plurality of signal and error-correcting codes combinations.
MCS helps to satisfy the conflicting requirements for productivity and reliability of
radio channels without reducing energy efficiency.
MCS is the subject of intense theoretical research. At the same time, MCS quickly
find practical applications and implementations in real communication systems. The
reason of such keen interest and practitioners in MCS – it’s the need of simultaneous
improvement of reliability and data rate, with substantial limitations on power and
frequency band. This increase can be achieved by improving the methods of signals
transmission and reception (demodulation and decoding). In turn, it requires the
establishment of a complicated constructions and functionality of transmitter and
receiver equipment.
The best combination of modulation and error-correcting coding provides an
efficient use of communication channel resources.
The most important problem in the MCS construction is the modulation and
coding methods matching and selection, which provides a high data rate and reliability.
The task of finding the best MCS is one of the most difficult tasks in the construction
of wireless communication systems.
