Abstract
We evaluate MUSIC, LMS, and the Goertzel algorithms for dual-tone
multiple-frequency estimation.
We rate their computational requirements, estimation errors, and their
compliance with the CCITT Q.23 and Q.24 standards through MATLAB simulations
and real-time implementations on the ADSP-2101 and Motorola 56001 processors.
