ETSI - TR 146 055

Digital cellular telecommunications system (Phase 2+); Performance characterization of the GSM Enhanced Full Rate (EFR) speech codec

inactive
Organization: ETSI
Publication Date: 1 October 2014
Status: inactive
Page Count: 28
scope:

The present document gives background information on the performance of the GSM enhanced full rate speech codec. Experimental results from the Pre-selection and Verification tests carried out during the standardization process by the SEG (Speech Expert Group) are reported to give a more detailed picture of the behaviour of the GSM enhanced full rate speech codec under different conditions of operation.
