“…Through the IIR filter, the speech signal frequency are centered between 0.5～2.0 kHz, after 15 kHz sampling into DSP, 28 kHz carrier frequency is selected. Frequency shift modulation algorithm uses single side-band modulation [5,6] , realization method are shown in figure 6. The modulated signal is transmitted to bone conduction headphone by the DA conversion.…”

In view of the fact that the traditional gas conduction hearing AIDS does not function to the patients with ear canal jams, this paper introduces a kind of ultrasonic hearing devices. Through the ultrasonic voice signals sent by the bone conduction modulation, the hearing-impaired patients can get a certain degree of hearing. The device, with TM320VC5410 as signal processing unit, modulates the voice signals with ultrasonic and transmit the signals through the bone conduction headphone to human auditory nerves. The experimental results show that the hearing devices can help patients with severe deafness recognize sound and voice. As a result, it is of high application value.

A new optical wireless full-duplex communication system was proposed and demonstrated. DSB modulation was used in this system and then the lower side band was reflected as the uplink optical carrier, achieving the wavelength reuse by the FBG. At the same time, a SSB modulated downlink data was got to reduce the impact of fiber dispersion. Pilot tone injection was also used in base station to generate a new local oscillator (LO), for the uplink signal down conversion, so that the base stations did not need to configure additional LO, simplifying the complexity and cost of base station. The uplink and downlink eye diagram show that the system had well performance against the dispersion and can support long-distance transmission.
