Abstract: PURPOSE: A communications method in a multiple sensor node environment using a time reversal technique for improving system capacity is provided to reduce the intensity of an interference signal affecting each sensor node and optimize the SNR. CONSTITUTION: A center node receives a different orthogonal signal from each sensor node(S100). The center node divides the signal of each sensor node by using the received different orthogonal signals. The center node obtains channel information based on the divided signal. The central node applies a time reversal technique to the channel information. The center node transmits the different signal to each sensor node(S200).

Abstract: PURPOSE: A user selection method of subspace interface alignment in a multi cell uplink system is provided to enable a user to directly measure an interference which influences a neighboring cell in multi cell environment and to select user who will apply an interference alignment, thereby reducing the calculation complexity. CONSTITUTION: Each user measures the amount of interference which influences to a neighboring cell(S100). Each user is aligned in bigger mount of measured interference order(S200). Each aligned user calculates the sum capacity of the whole system when applying the subspace interference alignment(S300). Relevant user is selected if calculated sum capacity is over a predetermined size(S400).

Abstract: PURPOSE: A dynamic time allocation method in cooperative multiplexing with a partial relaying system is provided to optimize the length of the time interval in order to have maximum system capacity by the variable location of the repeater. CONSTITUTION: An entire transmission frame interval of a repeater cooperative multiplexing technique is divided by the time interval(S100). A channel capacity of the divided each time interval is obtained(S200). The system capacity at the part relay cooperation multiplex technique is calculated by using the channel capacity of each time interval(S300). The time interval capable of maximizing the system capacity is calculated(S400).
