Performance Evaluation of Two-hop-relay WCDMA Cellular Systems
This article firstly introduces a new architecture of two-hop-relay WCDMA cellular system, and builds the analytical model of this system. Then based on this model, we get the average downlink transmission rate and the call blocking probability of packets of the system respectively. Finally, through numerical calculation, we analyze the impact of the various parameters on the performance of the two-hop-relay WCDMA cellular systems, and compare the systems performance with the traditional WCDMA cellular systems without relaying and the two-hop-relay WCDMA cellular systems with congestion control. Our results show that the two-hop-relay WCDMA cellular outperforms the traditional WCDMA cellular systems in terms of the average downlink transmission rate, but increases the call blocking probability of packets of the system simultaneously, and the two-hop-relay WCDMA cellular systems with congestion control can decrease the call blocking probability further, while preserve the improvement for the average downlink transmission rate.
