“…When n clients evenly share the links and TCP is used, the optimum receiver's advertised window size W can be obtained by: (2) where, RTT is the round trip time between the server and the clients, TI is the round trip time between the server and the gateway, and T2 is the round trip time between the gateway and the clients. For the communication system using a radio link, the packet loss due to transmission error is inevitable.…”

“…Thus the convolutional coding (R=1/2, k=7) I Viterbi decoding is chosen as forward error correction (FEC) in radio physical layer and a partial units of a selected Iframe repeat control (PUSIR) [2] is adopted as automatic repeat request (ARQ) in data link layer (LAPDM) between the mobile station and the PDC-P network ( Figure 2). PUSIR is developed for the PDC-P system and the parameters of this function are modified for this system to cope with the satellite propagation delay…”

“…This system provides voice and 4.8kbps datdfax services for those who are out of a terrestrial mobile communication service area, such as maritime user. The mobile packet communication system called PDC-P [2] [3] was developed and commenced the 28.8kbps packet service in 1998 for terrestrial users. The number of PDC-P subscribers shows a steady increase and the system is also serving as a platform for i-mode service.…”

This paper outlines the N-STAR satellite mobile packet communication system and its key features and presents the throughput performance. n e system was developed to have the compatibility with the terrestrial mobile packet communication system called PDC-l? The system has been providing Internet and Intranet access service for those customer where the terrestrial system does not cover, mainly maritime users, since March 2000. To realize the high throughput communication system economically, an asymmetrical channel arrangement and an efficient return link channel assignment scheme were developed. High efficiency FEC and ARQ were also adopted at radio link to cope with GEO satellite propagation delay. The field test reveals this system has achieved a good throughput performance.
