| Abstract(in English) | Recently, we proposed a random transmit power control (TPC) to increase the uplink capacity of Direct Spread Code Division Multiple Access (DS-CDMA) wireless packet access using Rake combining. Furthermore, we evaluated the combined effect of random TPC and inter-path interference (IPI) cancellation and showed that a significant throughput improvement can be achieved if the IPI can be sufficiently suppressed. It is known that frequency-domain equalization (FDE) is a well-known technique to suppress the IPI. In this paper, we derive an expression for the received signal-to-interference plus noise power ratio (SINR) for a DS-CDMA wireless packet access using FDE and random TPC and evaluate its system throughput by numerical computation. We also compare the system throughput when using Rake combining with that using FDE to discuss the IPI suppression effect of FDE. |
