Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0029] The invention provides a cochlear implant radio frequency data transmission method. The method digitally encodes the radio frequency signal to form a specific format frame, and the specific format frame encapsulates discharge stimulation parameter information.

[0030] The specific format frame obtained by the digital encoding method of the present invention adopts two stimulation phase cycle transmission methods, and each stimulation phase cycle is composed of phase synchronization code, data code, check code and extended carrier, and is transmitted within the stimulation cycle...

Abstract

The invention relates to a radio frequency data transmission method for an artificial cochlea. According to the method, radio-frequency signals are subjected to digital coding, then frames with the specific format are formed, discharge stimulation parameter information is packaged in the frames with the specific format, the frames with the specific format adopt the transmission mode adopting two stimulating phase position periods, and each stimulating phase position period is composed of phase synchronization codes, data codes, checking codes and extension carrier waves. Compared with the prior art and compared with the traditional ASK modulation and PWM coding method, the method provided by the invention has the advantages that the reliability is high, the decoding circuit is simple, theantijamming capability is strong, the data transmission rate is high, and the power consumption is low.

Description

technical field [0001] The invention relates to the technical field of cochlear implants, in particular to a cochlear radio frequency data transmission method. Background technique [0002] Implantation of cochlear implants is currently an effective means for patients with severe and profound hearing impairment to regain hearing. A cochlear implant consists of two parts: an implant and a sound processor. The implant is surgically implanted into the patient's cochlea, and has an electrode array connected to the nerve cells in the cochlea that sense hearing; the sound processor captures external sounds and produces them after processing. The radio frequency signal is directed to the implant; the implant obtains power through electromagnetic induction and receives radio frequency data, and obtains the characteristics of the sound by analyzing the data, and then generates a corresponding discharge on the electrode array, thereby stimulating the auditory nerve cells to enable the...
