Abstract

We have analyzed the performance of TCP in the CDMA mobile communications systems with the adaptive modulation and coding (AMC). An embedded Markov chain has been formulated and the system throughput has been derived. The wireless channel using AMC is characterized with not high error rate but highly varying bandwidth. Due to time-varying bandwidth, timeout events of TCP occurs more frequently, which leads to the throughput degradation. Since our system model is characterized by the forward link high speed data transmission using AMC, the results reported in this paper can be used as a guideline for the design and operation of HSDPA, 1xEV-DO, and 1xEV-DV.
