摘要： A mobile communication apparatus having an antenna array and a mobile communication method performed in the mobile communication apparatus, wherein the mobile communication apparatus includes a base station and mobile station, each having an antenna array. The mobile station measures the downlink characteristics of a channel for each antenna from a signal received from a base station, determines long-term information in which the correlation property of the channel for each antenna has been reflected from the measured downlink characteristics, transforms the long-term information into a feedback signal, and transmits the feedback signal to the base station. The base station receives the feedback signal, restores the long-term information from the received feedback signal, performs basis mapping and basis transformation on a dedicated physical channel signal using the restored long-term information, adds the basis-mapped and basis-transformed signal to each of pilot channel signals, and transmits the addition results to the mobile station.

摘要： Disclosed is a wireless communication apparatus and method for a multiple transmit and receive antenna system using multiple codes. In suggested detection algorithm, a successive interference cancellation (SIC) scheme is employed in both an antenna domain and a code domain by successively canceling multi-code interference (MCI). An effective transmit power allocation method suitable for the detection algorithm is suggested. Transmit power allocated to each code is calculated. The transmit power is determined as a simple ratio of power of a certain signal to power of a next code signal. Based on the calculated code transmit power, transmit power for each transmit antenna is allocated. Thus, information about transmit power calculated at a receive end is feedback to a transmit end through a feedback channel.

摘要： An optimum perturbation apparatus and method in a multi-antenna, multi-user communication system are provided. In the optimum perturbation method, upon receipt of modulation symbols, channel responses are decomposed into eigenvalues and eigenvectors by Single Value Decompositin (SVD) and a distortion value of the modulation symbols is estimated using the eigenvectors and the eigenvalues to minimize noise and interference power. The modulation symbols are precoded by combining the modulation symbols with the estimated distortion value.
