Cochlear implants have achieved great success in restoring hearing to profoundly deaf people. New generation implants pose more restrict requirements on processing precision and make traditional cochlear systems insufficient to deal with the large amount of data which should be transmitted via the wireless link. A new cochlear system with implant DSP is proposed to address the data rate problem. This system needs to transmit only voice-band signals with a data rate of 100 Kbps and the data rate bottleneck is removed for future development. By optimizing the speech processing algorithm and the inductive wireless link, the power consumption of this system increases less than 10% when compared with the traditional system
