Computational complexity estimate of a DSR front-end compliant to ETSI Standard ES 202 212

This paper presents a computational complexity estimate of a distributed speech recognition front-end, compliant to ETSI Standard ES 202 212 and implemented at system-level in SystemC. This estimate allows to know which blocks of terminal front-end are more computational expensive, and therefore it may be useful, in an hardware implementation, to realize them with low-power ad-hoc hardware.
