  • This paper 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, the average downlink transmission rate and the call blocking probability of packets of the system are obtained respectively. Finally, through numerical calculation, the impact of the various parameters on the performance of the two-hop-relay WCDMA cellular systems is analyzed, and the systems performance is compared with the traditional WCDMA cellular systems without relaying and the two-hop-relay WCDMA cellular systems with congestion control.
