Abstract: Disclosed herein are systems and methods for self-formation and self-management of full-duplex communication networks. In an embodiment, a communication device determines whether there is an available self-assignable device-data time slot. If there is, the device selects an available time slot for outbound transmissions, updates its network-status table to associate the selected time slot with a device identifier of the communication device, and transmits outbound device data during the selected time slot of at least one ensuing frame. The device also, during each of a plurality of ensuing frames, makes a determination as to whether to transmit a maintenance packet during a shared time slot of the current frame. If the determination is made in the affirmative, the device transmits such a packet during that shared time slot. Each such packet contains at least a subset of the network-status table.

Abstract: The present disclosure relates to a system and method of cancelling feedback in a vehicle communications system. The system and method may adjust a phase and a polarity of the microphone signal to produce an inverted microphone signal having a shifted phase. A speaker signal may be summed with the inverted microphone signal to cancel out at least a portion of a microphone signal component of the speaker signal.

Abstract: A communications system for a vehicle user is provided. The system comprises a portable transceiver which the vehicle user can easily carry on his or her person and a vehicle-mounted transceiver. The portable transceiver is capable of communicating with the vehicle-mounted transceiver. Audio information contained in a transmission from the portable transceiver may be retransmitted by the vehicle-mounted transceiver either to a public address system or a second vehicle-mounted transceiver.
