Simulation-Based Performance Analysis of HSDPA for UMTS Networks

This paper investigates the performance of TCP over High Speed Downlink Packet Access (HSDPA) link in the third generation Universal Mobile Telecommunication System (UMTS). The throughput performance of TCP has been considered with both round robin and maximum carrier-tointerference scheduling schemes. A simulation based approach is adopted to determine the total cell throughput, both under ideal and Rayleigh fading conditions. Simulation results show that, HSDPA can effectively provide high throughputs, but with fairness depending upon the scheduling mechanism.
