摘要
The present invention concerns a system for transmitting data from a transmitter comprising at least two transmitting antennas, an encoder following an error correcting code structure and a transmit beamforming technique to a receiver comprising at least two receiving antennas and a decoder defined according to the error correcting code structure over a transmit beamformed MIMO channel. This invention aims to achieve high data rate and guaranty a target diversity and high performance while keeping the receiver complexity low. Indeed, the diversity reduction may be overcome by including an algebraic linear precoder which linearly combines modulation symbols at the transmitter side.;It is an object of the invention to determine the relationship between the precoding size, the parameters of the transmit beamformed MIMO channel, and an achievable diversity order. Then, the precoding size can be selected to achieve a target diversity order of the system.;As the complexity of the detector increases with the precoding size, such a relationship between the precoding size, the parameters of the transmit beamformed MIMO channel, the error correcting code rate and a target diversity order helps in finding the minimal precoding size that allows to achieve the target diversity order and a reduced complexity of the receiver.;An algebraic lattice reduction is used at the receiver in conjunction with an adapted linear precoder structure at the transmitter to further reduce the complexity of the receiver while guarantying to observe the target diversity order at the output of the receiver.
