A process and corresponding system for encoding and decoding digital data in analog signals is disclosed. Digital data values are represented by concurrent combinations of distinct audio tones, which combine to create chords. The chords have multiple identifiable parameters that can be modulated to represent the data values. For instance, the modulated chords can include a concurrent combination of distinct tones that each have a different frequency and a different starting time. The frequencies of the tones and the starting times of those tones can be modulated to create unique combinations that represent respective data values. As such, analog audio content of a given chord can be used to represent a particular data value and the analog audio signals can be transmitted between nodes in a communication network in order to communicate that data value.

Chord modulation communication system

A method and system for managing the allocation of uplink transmission resources. A first subscriber device may communicate with a second subscriber device over a local communication link. The first subscriber device may also transmit data over an air interface to a radio access network (RAN) serving the first subscriber device, with the first subscriber device serving as a proxy between the second subscriber device and the RAN. In response to the data including first data originated by the first subscriber device and second data originated by the second subscriber device that is received by the first subscriber device from the second subscriber device over the local communication link, the first subscriber device may be arranged to apply a different transmission priority for the transmitting of the first data over the air interface than for the transmitting of the second data over the air interface.
