Digital signal transmitting method for orthogonal frequency-division multiplexing system, involves determining determinist matrix representing covariance matrix by considering statistic information including statistic parameters

摘要

The method involves obtaining source vectors each comprising a source symbol, and allocating a power delivering balanced symbols. Channels (13) are formed to multiply each balanced symbol by an allocation vector, where the vectors are represented by a allocation matrix. A determinist matrix representing a covariance matrix is determined by considering statistic information representing transmission channel between transmitting and receiving antennas, where the information includes a three statistic parameters. Independent claims are also included for the following: (1) a computer program product comprising program code instructions for executing a digital signal transmitting method (2) a device for transmitting a digital signal.
