Abstract: The disclosure relates to a cochlear implant system, and more particularly, the disclosure relates to a processor unit which includes a switching mean configured to switch between using a fixed stimulation frame onset or a variable stimulation frame onset for frame coding a plurality of stimulation pulses into a one or more stimulation frames.

Abstract: A cochlear stimulation system for determining a Temporal Fine Structure (TFS) parameter of a spectral component of an incoming acoustic signal is provided. The system comprises a transducer receiving an incoming acoustic signal, and wherein a sampled audio signal of length N samples is provided based on the incoming acoustic signal, a storing unit including a plurality of window frequency differences and/or a plurality of window energy level differences. The system further comprises a signal processor for estimating the TFS parameter of the full frequency range of the sampled audio signal by locating a main spectrum sample of the plurality of spectrum samples having a maximum energy level within a range of frequencies centered around the main spectrum sample, and determining the TFS parameter based on the energy level difference for one or more of the spectrum samples of the group of spectrum samples and the window function.
