Abstract
This paper presents the design, development, simulation and test of a directional telemetry system for cochlear implants using FPGA. We used Manchester codification and ASK modulation in order to achieve a high transmission speed. The design was simulated using the System Generator for FPGA by Xilinx and Simulink developed by Mathworks. Also, the design was emulated using the ISE design software by Xilinx. The design has been tested under noisy environment. The design was optimised so as to obtain a power consumption equal or less than the maximum allowed in the receiver. We achieved the use fewer components of the FPGA. As a result, the telemetry system has been designed to meet with specifications for use it in the development of a prototype of cochlear implant for research purposes.
