| Abstract: | The research of PHS data service is becoming more and more importance due to being saturation of PHS voice service market. The attention is focused on PHS data service simulation system which is implemented with RTOS. Based on it, the performance of future PHS data service which applies high rank modulation and error control encoding technology is studied. The emulation result is presented and compared. The conclusion that the data transmission performance is improved by joining ARQ in data - link layer with adaptive modulation and encoding in physical layer is drawn. At last, further researching direction is discussed. |
