Abstract
A system for wireless data transmission is presented based on the use of an adaptive algorithm for processing spatial-temporal signals using antenna arrays. To solve the problem of increasing the maximum data transmission speed and providing a low probability of error in data transmission under multipath conditions, technologies such as MIMO (Multiple input-Multiple output) and OFDM (Orthogonal Frequency Division Multiplexing) were used. The adaptation process is based on the formation of an equivalent directional pattern of the amplitude array antenna in the direction of the arrival of the signal with the highest power along one of the paths in the channel. The results of the research showed that application of the adaptive algorithm on the receiving side allows to significantly reduce the probability of bit error, thereby increasing the throughput in the wireless data channel.
