Radio transmission method within closed space uses simultaneous transmission and reception antenna elements and space-time encoders and decoders

摘要

The radio transmission method has a number of digital data streams converted into a number of data signals via a space-time coding using a selected data modulation format, for parallel transmission via a frequency-limited multi-path transmission channel, with estimation of the space-time characteristics of the transmission channel and space-time decoding of the received signals for restoration of the digital data streams. Each transmission channel is provided with a known pilot signal with a superimposed data signal in the form of a marked pilot sequence, for measuring the complex channel matrix elements, for analogue weighting of the reception signals for restoration of the digital data streams. An Independent claim for mobile radio transmission system is also included.
