Method and system for introducing frequency selectivity into transmissions in an orthogonal frequency division multiplexing network

摘要

A method of introducing frequency selectivity into transmissions in an orthogonal frequency division multiplexing network is provided. The method includes generating a symbol. A plurality of delayed symbols are generated based on the symbol. The delayed symbols are transmitted from multiple transmit antennas. The symbol delay values may be different for different users depending upon the users' channel characteristics.
