Algorithm of Joint Adaptation on Reception and Transmission in the Communication System on the Basis of Antenna Arrays


V.P. Fedosov, D.O. Ternovoj

Results of development and probings of the adaptive algorithm in a MIMO-communication system (multiple-input multiple-output) simultaneously both on transmitting are presented, and on the receiving the ends of a link of wireless access on the basis of the antenna lattices, allowing to boost transmission capacity of the channel without magnifying of an occupied frequency band. Algorithm development is made in the assumption, that Rayleigh channel possesses slow fades and does not change the parameters within time of transmission of control (training) and information parcels. The control parcel is known on a communication line receiving end. The algorithm provides shaping of beams of blocks of the receiving and transmitting antenna lattices directional on a propagation path of an electromagnetic field, providing transmission of the maximum signal strength. Reception and a signal transmission are made in the conditions of the active hindrance caused by hit of a signal of other operator because of non-linearity of its transmitter. Modeling has shown high efficiency of the algorithm, allowing to lower on some usages probability of a bit error by transmission of an information signal at influence of active hindrances.
