Abstract
This paper presents the use of the OFDM (Orthogonal Frequency Division Multiplexing) modulation technique in the design and simulation of a telemetry system for a cochlear implant. Data were processed through the Simulink module of MATLABTM. High transmission speed and high spectral efficiency were achieved with this design and simulation. Two types of OFDM were studied and compared regarding spectral efficiency and noise immunity, and the superiority of OFDM modulation using the QAM (Quadrature Amplitude Modulation) method was shown over OFDM, which uses the DQPSK (Differential Quadrature Phase Shift Keying) modulation method.
