Abstract
A method and device for transferring OFDM symbols representative of at least a first and a second stream from a source including a first number of antenna to at least one receiver. The source demultiplexes the first stream to extract at least one first pilot sequence and first data and the second stream to extract at least one second pilot sequence and second data, multiplies the at least one first pilot sequence and first data by a first coefficient, the at least one second pilot sequence and second data by a second coefficient different from the first coefficient, sums first multiplied data and second multiplied data, multiplexes the sum, the at least one first and second multiplied pilot sequences to form the OFDM symbols, and transfers the OFDM symbols.
