    Abstract: The telecommunications systems, software, and methods are for power-efficient coordinated multipoint transmission, particularly in millimeter-wave small cells. The systems, software, and methods apply portfolio theory to determine an allocation of power to a plurality of transmitters in communication with one or more receivers in a joint transmission configuration, such as a MMW or BF-MMW joint transmission configuration. The systems, software, and methods apply portfolio theory to determine an allocation of power to a plurality of transmitters such that a mean received power, associated with a certain level of variance, is maximized, or the variance of received power, associated with a certain level of mean received power, is minimized.

    Abstract: A resource allocation method is provided for a non-orthogonal multiple access distribution of access network users communicatively coupled to a single transport medium. The method includes steps of allocating a first frequency and time domain resource to a first user and a second frequency and time domain resource to a second user of the access network users, obtaining channel information regarding a particular communication channel of the access network for which resources are allocated, grouping the first user with the second user based on an overlap of the first frequency and time domain resource with the second frequency and time domain resource, and assigning the first user to a different power allocation resource than the second user within the frequency and time domain overlap.

    Abstract: A communication system includes an earth station configured to receive a downlink transmission from a satellite and transmit an uplink transmission to the satellite. The communication system further includes a server in operable communication with the earth station, a beacon detector in operable communication with the server, an access point configured to operate within a proximity of the earth station, and a beacon transmitter disposed within close proximity to the access point. The beacon transmitter is configured to transmit a beacon signal to one or more of the server and the beacon detector. The beacon signal uniquely identifies the access point. The server is configured to implement a measurement-based protection scheme with respect to at least one of the downlink transmission and the uplink transmission.

    Abstract: A method of modulating a series of input digital symbols of a first modulation scheme is provided. The method is implemented by a transmitter and includes receiving a sequential series of samples of the digital symbols in a first domain of the first modulation scheme. The first domain is one of the time domain and the frequency domain. The method further includes determining a dual of the first modulation scheme. The dual has a second modulation scheme in a second domain that is different from the first domain the second domain is the other of the time domain and the frequency domain. The method further includes applying a 90 degree rotational operation to the second modulation scheme to generate a rotational modulation format, modulating the series of digital symbols with the generated rotational modulation format, and outputting the modulated series of digital symbols to a receiver.

    Abstract: A profile optimizing method is provided for a transmission of active subcarriers over a channel to user devices. The method includes steps of (i) obtaining a symbol mapping architecture for the set of profiles, (ii) calculating, from the symbol mapping architecture, a plurality of mapping orders for the set of profiles different from the logical order, (iii) determining, from the calculated plurality of mapping orders, a particular mapping order having a higher spectral efficiency than the logical order, (iv) reordering the respective codewords of the set of profiles to correspond to the particular mapping order, (v) re-mapping the symbol mapping architecture to a number of symbols corresponding to the reordered codewords, and (vi) transmitting the symbols to the population of user devices. The symbol mapping architecture includes a codeword for each profile of the set of profiles, and maps the codewords to a different number by logical order.
