RADIO TRANSMITTING/RECEIVING SYSTEM AND RADIO TRANSMITTING/RECEIVING METHOD

摘要

PURPOSE: A radio transmitting/receiving system and a radio transmitting/receiving method are provided to obtain a maximum space diversity gain by ensuring a high transmission ratio and removing correlation between channels. CONSTITUTION: A radio transmitting/receiving system comprises a transmitting unit(10) and a receiving unit(20). The transmitting unit includes a signal converter(11) for converting an input bit sequence into N-number of sub sequences; a channeling unit(13) for channeling the sub sequences by providing channeling codes to each of sub sequences; a transmitting beam forming unit(14) for providing weight values for formation of transmitting beam to the channeled sub sequences; and N-number of transmitting antennas(15) for transmitting signals of the channels provided with the weight values. The receiving unit includes M-number of receiving antennas(21) for receiving the signals transmitted from the transmitting antennas; a receiving beam forming unit(22) for providing weight values for formation of receiving beam to the signals output from the receiving antennas; an inverse channeling unit(23) for restoring sub sequences by inversely channeling the signals provided with the weight values; and a signal converter(26) for coupling the restored sub sequences and outputting an input bit sequence.
