Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] A multi-channel ultra-wideband communication transceiver (Chirp-UWB ultra-wideband communication transceiver) is composed of a transmitter and a receiver; the transmitter is composed of a digital gradient generator (Digital Gradient Generator), a digitally controlled oscillator It consists of a Digitally-Controlled Oscillator (DCO) and a Power Amplifier (PA). The receiver is composed of a low noise amplifier (LNA), a double-balanced (Double-Balanced) frequency demodulator, and a clock and data recovery (CDR) circuit. The establishment of the multi-channel communication mode is mainly based on the transmitter. Because the spectrum of the Chirp-UWB ultra-wideband transceiver is distributed in the wide space range of 6.25GHz to 10.25GHz, the frequency division multiplexing (FDMA) method can be used for this wide space to divide it into several channels to achieve ...

Abstract

The invention discloses a multi-channel ultra-wideband communication transceiver. The multi-channel ultra-wideband communication transceiver can be divided into four sets of sub-channels in the 6.75-10.25 GHz bandwidth, so that transmission processing of data can be carried out; therefore, a condition that multiple users or equipment work simultaneously can be satisfied; the multi-channel ultra-wideband communication transceiver is composed of a transmitter and a receiver; the transmitter is composed of a digital gradient generator, a numerically controlled oscillator and a power amplifier; and the receiver is composed of a low-noise amplifier, a double-balanced frequency adjustor and a clock and data recovery circuit. The multi-channel ultra-wideband communication transceiver disclosed by the invention can be divided into the four sets of sub-channels in the 6.75-10.25 GHz bandwidth, so that transmission processing of data is carried out; and thus, the condition that multiple users or equipment work simultaneously can be satisfied.

Description

technical field [0001] The invention belongs to the field of hearing aid design, and in particular relates to a transceiver applied to wireless binaural hearing aid communication, in particular to a situation where multiple users or multiple devices work simultaneously. Background technique [0002] According to data from the World Health Organization, hearing impairment is currently the largest category of people with disabilities. With the acceleration of social aging, the proportion and number of elderly people in China are rising rapidly, and the number of people with hearing impairment is increasing year by year, and the demand for hearing aids is also huge. [0003] Today's hearing aids face the development trend of diversification of signal processing functions and wireless interconnection with audio equipment. Traditional single-ear hearing aids cannot perform the function of hearing assistance well, especially when the patient's left and right ears have different d...
