Abstract: It is an objective of the current disclosure to design a novel communications system capable of offering improvement in channel capacity compared to current communications systems. To this end, the disclosure teaches how to add new information to a select number of Degrees of Freedom (DOF), through three design steps. All three steps aim to design the system such that the minimum required average received Signal-to-Noise Ratio (SNR) is reduced for a given desired capacity and for a given specified mask. The first design step identifies the select number of DOF required for achieving the desired capacity. The second design step enhances the contribution of the selected DOF by matching them to the specified mask. This step aims to have the transmitted signal comply with the specified mask. The third design step randomizes the DOF using a pseudo-random phase. This step aims to reduce the required average received SNR.

Abstract: Two inventive contributions are made for improvement of communications systems. A first derives the channel capacity of a Time-Limited (TL) system across a communications channel contaminated by interference and by noise. The potential increase in channel capacity compared to current communications systems is due to the availability of an arbitrarily large number of Degrees of Freedom (DOF) with finite access Time (FAT) in a TL system. A second takes advantage of the theory established in the first objective to design novel systems, referred to as Mask-Matched TL systems with FAT DOF, or MTF systems for short. The disclosure shows several embodiments of MTF systems where it is possible to improve the capacity of current communications systems, without having to modify or alter their Power Spectral Density, merely by taking advantage of their existing but unexploited FAT DOF through the 3 MTF design steps introduced in this disclosure.

Abstract: Systems and methods for uplink (UL) and downlink (DL) communications can improve channel capacity between one or more access nodes and one or more terminal nodes. The communications may utilize, for example, multi-user multiple-input multiple-output techniques with cooperation between access nodes. A network node may determine an ordering combination and associated pre-weighting values, provide the pre-weighting values to one or more terminal nodes, receive signals transmitted from the terminal nodes using the pre-weighting values; and process the received signals using the ordering combination and the pre-weighting values. Two constraints can be jointly used: a minimum performance constraint and a maximum transmit power constraint. Example systems search all possible ordering combinations to find a best combination, for example, the ordering combination that maximizes communication rates.

Abstract: Systems and method for adaptive constellation mapping determine transmission formats for simultaneous transmission from multiple transmitter chains. The adaptive constellation mapping can select a winning combination of mappings using distance metrics. The distance metrics can be calculated from estimated received signal constellations at a multi-layer receiver. The multi-layer receiver can separate the data received from each of the transmitter chains. Additional systems and method can determine a whether to use adaptive constellation mapping or an alternate transmission format. Further systems and methods can determine a transmit arrangement that include selection of which of multiple transmitters will be a part of an adaptive constellation mapping transmission, the number of layers that will be transmitted by each transmitter, the transmitter chains that will be used, and which of multiple antennas that will be used.
