Abstract
A communication system reduces power consumption of a radio receiver and/or ensures quality of signal transmission by using various modes of receiver operation. In one embodiment, the communication system is part of a hearing assistance system with a hearing aid including the radio receiver. In one embodiment, a mode of reception is selected during signal transmission based on a detected parameter indicative of quality of the signal transmission. In one embodiment, a hearing aid includes a radio receiver using independent sidebands to receive signals transmitted using each of an upper-sideband and a lower-sideband.
Claims25
A system for signal transmission to a hearing assistance device, the system comprising:
- a plurality of demodulators configured to demodulate a signal transmitted using one or both of an upper sideband (USB) and a lower sideband (LSB), the plurality of demodulators including:
- a double-sideband (DSB) demodulator configured to demodulate the signal transmitted using DSB;
- and
- a single-sideband (SSB) demodulator configured to demodulate the signal transmitted using SSB;
- a performance analyzer configured to detect a performance parameter being a measure of quality of the signal transmission;
- and
- a mode switch configured to select a demodulator from the plurality of demodulators using the detected performance parameter.
A method for signal transmission to a hearing assistance device, the method comprising:
- providing a hearing aid with a radio receiver capable of receiving a signal transmitted using one or both of an upper sideband (USB) and a lower sideband (LSB), the radio receiver configured to operate in a reception mode selected from a plurality of reception modes including a double-sideband (DSB) mode to receive the signal transmitted using both the USB and the LSB and a single-sideband (SSB) mode to receive the signal transmitted using the USB or the LSB;
- detecting a performance parameter being a measure of quality of the signal transmission;
- and
- selecting a reception mode from the plurality of reception modes using the detected performance parameter.
A method for signal transmission to a hearing assistance device, the method comprising:
- providing a hearing aid with an independent-sideband (ISB) demodulator;
- receiving first and second signals, the first signal transmitted using an upper-side band (USB), the second signal transmitted using a lower-sideband (LSB);
- demodulating the first and second signals using the ISB demodulator;
- and
- recovering data carried in the first and second signals for use by the hearing aid.
