METHOD FOR TRANSMITTING SIGNALS IN MULTI-ANTENNA SYSTEM PERFORMING CYCLIC DELAYS BASED ON A PLURALITY OF CYCLIC DELAY VALUE

摘要

A transmitting method in a multi-antenna system performing cyclic delays based on plural cyclic delay values is provided to improve diversity of the multi-antenna system by obtaining a maximum spatial multiplexing gain. A cyclic delay is performed according to plural cyclic delay values. The cyclic delay is performed according to the cyclic delay values for plural symbols which are to be transmitted through different transmission antennas. A data process is performed, so that at least one bit of plural bits corresponding to a first symbol is mapped to a second symbol. The processed symbols are transmitted by using plural subcarriers. At least one bit of plural bits corresponding to the first symbol is replaced. The symbols to be transmitted through different antennas are transmitted in different time slots.
