Title
MAC layer packet-length adaptive CLSP/DS-CDMA radio networks: performance in flat Rayleigh fading channel
Abstract
We analyse throughput-delay performance of an unslotted DS-CDMA packet radio network (PRN) using the channel load sensing protocol (CLSP) and packet-length adaptation. This paper shows that while error-correcting channel coding has not yet been effective in heavily correlated flat fading environments, adapting the length of radio packets to time-varying channel conditions is a simple adaptive technique for maintaining and improving the system performance and the energy efficiency of mobile terminals. In our modeling we study the correlation between fade duration statistics and packet length in a flat Rayleigh fading channel under the effects of imperfect power control and user mobility. The results are used to derive practical and robust adaptation mechanisms and performance characteristics. A number of numerical results is presented. This paper lays the groundwork for exploiting adaptive radio possibilities on media access control (MAC) layer in unslotted DS-CDMA PRN.
