MIMO RECEIVER INCLUDING ONE OR MORE ADDITIONAL RECEIVING PATHS.

摘要

PROBLEM TO BE SOLVED: To implement a receiver including at least one nore excessive receiving path than the number of a transmitting antennas used for transmitting a signal received with the receiver (for example, a radio OFDM signal) in a multi-input/multi-output (MIMO) System.

SOLUTION: Each receiving path utilizes recursive filtering and generates each subcarrier signal. A processor converts each subcarrier signal from a different receiving path to a first group of of a subcarrier signal corresponding to each transmitting OFDM signal.The first group of the subcarrier signal includes a hopeful signal and a CCI depending on the situation. The processor also generates a 2nd group of the subcarrier signal corresponding to the CCI.The processor subtracts a partial of the 2nd group of subcarrier signal from each of the first group of the subcarrier signal, and generates a restored OFDM signal with which the CCI was reduced.
