Annotations languages:

A brief description of the features of OFDM signals, determine a list of possible signs of identity. Improved correlation method for estimating key parameters pas signals, based on the cyclic prefix signal structure by binding began intervals orthogonal to the reference frequency grid. The simulation showed possibility of interference-signal demodulation based on solving systems of linear algebra equations (SLAE).
