More Information
Summary: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.
