Packet Discarding

<span>It is generally considered that remote and rural telephone users generate less traffic as compared<span> to urban area users. This lowers the attraction of investment in rural areas by the<span> telecommunications companies and service providers. The financial implications of wiring a<span> vast area for low telephone traffic causes most telephone service providers to ignore those<span> regions. Still, it is known that telecommunications are essential to the economic development of<span> a region and that traffic increases rapidly as soon as the service is available. A satellite–based<span> telephone network can provide efficient long distance telephone service to remote rural<span> communities at a lower cost than land-based wired networks in most cases. Mobile satellite<span> systems already provide this service, but are limited in capacity and charge high per-minute fees<span> for the satellite link. Small earth stations and GEO satellites can provide this service more<span> efficiently and at lower cost. On top of that, bandwidth efficient multiplexing with compressed<span> speech, Voice Activity Detection (VAD) and Packet discarding methods can even further reduce <span>the cost of service for the users in rural areas. In this paper, Statistical Time Division Multiplexer<span> (STDM) architecture was simulated. Two packet discarding methods, random packet discarding<span> and cyclic packet discarding are used to maximize bandwidth utilization along with VAD.<span> Results indicate that considering monologue speech source, with 80%, activity for each 6.4 kbps<span> sources, on a channel of 64 kbps, 12 users can be allowed to be multiplexed instead of 9,<span> therefore a Digital Speech Interpolation (DSI) advantage of 1.33 is achieved with 3% packet<span> loss. Furthermore, it is observed that cyclic packet discarding technique perform better than<span> random packet discarding in terms of subjective quality<br /><br class="Apple-interchange-newline" /></span></span></span></span></span></span></span></span><br /><br class="Apple-interchange-newline" /></span></span></span></span></span></span></span></span></span></span></span></span>

A comparative study of on-off characteristics of conversational Bangla and English speech over a telephone channel The existing ‘speech interpolation’ technique used in some speech transmission systems has been developed for the English language. In order to explore the possibility that different settings of the parameters might be more appropriate for other languages, the on-off speech statistics of conversational Bangla speech over a telephone channel were collected. A comparative study of the on-off characteristics of Bangla and English speech is presented.
