Cochlear implant (CI) patients have difficulty
understanding tonal languages which use pitch
variations to convey meaning because of poor pitch
perception. The ability of CI patients to communicate
in noisy environments is severely degraded.
Therefore, pitch-detection and (spatial) noise
suppression is of importance to current cochlear
implant devices. This thesis provides the details of
real-time implementations that address these
concerns. A pitch-detector was implemented to
estimate the pitch and a beamformer was implemented
to suppress spatial noise. The pitch-detection and
