Abstract

Details the subjective performance of various modulation schemes and speech processing techniques with application to the mobile satellite service. The comparison is based on a mean opinion score (MOS) assessment of voice quality with measurements drawn from a number of recent publications and laboratory measurements. Of particular interest is the performance of an analogue form of linear modulation (ACSSB) when compared with a digitised voice source used in conjunction with an appropriate data modulation system. It is found that for a given bandwidth/power budget, the linear analogue system will always outperform the digital equivalent for the present generation of voice coder technologies. The performance gain is most dramatic in a fading (Ricean) environment
