Abstract: The present subject matter includes a system for communications between a transmitter and a receiver. In various embodiments, the system uses a sleep interval to allow the receiver to go to sleep between wake up times to “sniff” for transmissions from the transmitter. The system adjusts the length of the preamble of the transmitted signal or a repetition of packets to allow the receiver to detect a transmitted signal based on drift in the clocks of the system. In various embodiments, a receive channel is changed if a signal is not received at a prior channel selection. In various embodiments, the transmission is determined by detection of an event. In various embodiments, the event is an ear-to-ear event. In various embodiments, the receiver and transmitter are in opposite hearing aids adapted to be worn by one wearer.

Abstract: The present subject matter includes a system for communications between a transmitter and a receiver. In various embodiments, the system uses a sleep interval to allow the receiver to go to sleep between wake up times to “sniff” for transmissions from the transmitter. In one variation, the system repeats a transmission for at least a duration of a wake interval. In various embodiments, a receive channel is changed if a signal is not received at a prior channel selection. In various embodiments, the transmission is determined by detection of an event. In various embodiments, the event is an ear-to-ear event. In various embodiments, the receiver and transmitter are in opposite hearing aids adapted to be worn by one wearer.

Abstract: Calibration methods and structures are provided for wireless communications devices that compensate across a signal bandwidth for relative gain and phase errors between spatial communication channels while utilizing existing transceiver structures and facilitating the use of frequency-domain spatial processing. The methods and structures are directed to time-division duplex (TDD) systems, and are particularly suited to those that incorporate orthogonal frequency division multiplexing (OFDM).
