    摘要: Disclosed is a method for deciding a signal detection order in a mobile communication system that supports an adaptive modulation technology. The detection order that maximizes a channel, in which a product of the minimum symbol distance for each modulation rate and the effective SINR becomes minimum, maximum is selected by obtaining the effective SINR and performing a bit allocation with respect to the detection orders of each detection order, and thus an average error probability can be minimized. In the case in which the number of antennas is increased, the detection orders of all the possible cases are not considered, but the detection order that maximizes the channel, in which the product of the minimum symbol distance for each modulation rate and the effective SINR becomes minimum, is selected with respect to a forward ordering and a reverse ordering.

    摘要: Disclosed herein is a scheduling method and apparatus based on eigen values robust against spatial correlation in a mobile communication system supporting multiple users by use of multiple transmit/receive antennas. A user terminal estimates channel characteristics from the transmit antennas to the user terminal, decomposes the estimated channel characteristics into receive channel characteristics and transmit channel characteristics, and feeds back a transmit principal eigen vector to the base station (BS). The BS selects a predetermined number of user terminals having the least correlation using the feedback principal eigen vectors from a plurality of user terminals, constructs a user precoding matrix by combining the principal eigen vectors of the selected user terminals, multiplies data streams for the selected user terminals by the user precoding matrix and transmits the multiplied data to the selected user terminals.

    摘要: A user allocating apparatus and method in a multiple antenna mobile communication system supporting multi-user diversity is provided. Each user calculates effective Signal-to-Interference Noise Ratios (SINRs) and bit loading over every possible detection order and selects a detection order maximizing the number of channels with a minimum product of the minimum symbol distance of a modulation scheme and an effective SINR, thereby minimizing an average error probability. A base station receives detection orders from users and selects a user with a maximum detection order value. The base station then transmits data to the selected user using modulation schemes determined by the user for the transmit antennas.
