| titleOfInvention | Maximizing energy efficiency in non-linear precoding using vector perturbation |
| abstract | A signal precoder is provided for use with a signal transmitter comprising a plurality of antennas for transmitting a plurality of signal components to a receiver over a communications channel in which one or more properties of the communications channel are described by a plurality of values which scale t he components of the signal in a plurality of dimensions during transmission, in which the precoder is arranged to perform non-linear precoding on a source signal prior to signal transmission, the precoder comprising a balancer for determining a plurality of optimised amounts of signal perturbation required to be applied to one or more source signal components to minimise the energy of the signal transmission, when respectively scaled by each of the values describing one or more properties of the communications channel, and a selector for selecting which of the optimised amounts of signal perturbations results in signal transmission having the least energy when scaled by the values describing the one or more properties of the communications channel, wherein the precoder is arranged to perform non-linear precoding on the source signal by applying the selected optimised signal perturbation to the source signal and to output the precoded signal. The embodiments of the present invention offer near-optimum detection performances and linear computational scalability simultaneously. The present invention also provides a signal transmitter, a communications system and a signal receiving method. |
