Abstract: PURPOSE: A method for modifying a code book of a multi input/output preprocessing based on a code book which plans to relax the interference is provided to prevent funcation deterioration in a closed loop MIMO transmission based on code book considering neighboring communication device interference through demodulating of a code book. CONSTITUTION: A second receiver presumes a channel to first transmitter by usage of a reference signal(S102). If the first transmitter presumes a channel, the first transmitter calculated a reception correlation matrix through the estimated channel(S103).

Abstract: PURPOSE: An apparatus and a method for selecting a precoding matrix are provided to minimize error probability of a signal vector to be retransmitted by feeding back the precoding matrix selected from a code book to a transmission terminal. CONSTITUTION: A communication unit(110) is connected to a transmission terminal and transmits and receives a signal vector or retransmission request signal. A combination unit(120) combines a first signal vector and a second signal vector and checks whether an error exists in the second signal vector. An operation unit(130) selects the precoding matrix by operating an ESNR(Effective Signal to Noise Ratio) for retransmitting the second reception signal vector to the transmission terminal according to the combination method of the first signal vector and the second signal vector.

Abstract: PURPOSE: A method for designing a pilot and a resource allocation block in a high speed movement environment is provided to improve performance of a system by allocating the resource allocation block to a user only if necessary. CONSTITUTION: A resource allocation block under a low speed movement environment is connected. If the user is not supported in a high speed movement environment basically, the resource allocation block under the low speed movement environment is used. If the user is supported in the high speed movement environment, the resource allocation blocks under the low and high speed movement environments exist at the same time. The resource allocation blocks under the low and high speed movement environments are arranged in the scheduling by matching the movement environment of each user using the OFDMA method.
