Abstract :
MUROS using high order modulation (HOM) is one of techniques for improving speech efficiency for 3GPP GERAN evolution. However, the conventional HOM for MUROS scheme shows high complexity because of the change of modulation format. Therefore, in this paper, an improved HOM scheme for the MUROS is proposed which employs a repetition transmission using surplus bits.
