Abstract

The properties of inter-frame placement for immittance spectral frequencies (ISF) are studied. As a result, a novel efficient method of ISF calculation is proposed. It is shown that average number of operations is reduced in 2.3 in comparison with standard grid approach. Besides, the observed maximum number of operations is 1.7 times lower than the minimum operations number of AMR-WB approach. The performance in different frame error rate (FER) environments is analyzed. The method was implemented in fixed-point wideband vocoder and showed stable performance.
