TL;DR: In this paper, the authors proposed a method for configuring transmission antenna groups in a mobile communication system with multiple transmission antennas and multiple reception antennas, which includes the steps of: receiving a first matrix having a size of "N t ×N t " which corresponds to N t number of transmission antennas, fedback from the mobile terminal, generating combinations of sub-matrixes of the first matrix corresponding to N r number of reception antennas.

TL;DR: In this paper, a communication method in an FH-OFDM communication system having a plurality of BSs is provided, where a predetermined number of pilot pattern groups are generated, each pilot pattern group having a fixed number of different pilot patterns for pilot transmission.

TL;DR: In this paper, a method for assigning a single frequency sub-channel to a plurality of mobile stations in an OFDM system utilizing SDM (Spatial Division Multiplexing) with multiple transmit/receive antennas is proposed.

TL;DR: In this paper, a spatial modulation method and transmitting and receiving apparatuses using spatial modulation using an index of an activated antenna and a signal modulation constellation as an information source are provided.

TL;DR: In this article, a user allocating apparatus and method in a multiple antenna mobile communication system supporting multi-user diversity is provided, where each user calculates effective Signal-to-Interference Noise Ratio (SINR) 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.
