The Performance Comparison between WiBro and HSDPA

We evaluated and compared the performance of WiBro and HSDPA, which are the most competitive systems for high data rate mobile service. WiBro is the new Korean standard for wireless and broadband portable Internet. Evaluation was done by cell-planning tool, link, and system level simulation. HSDPA showed the inferior performance in multipath fading channel, while WiBro did nearly good performance. WiBro provides higher data rate transmission in multipath fading channel due to OFDMA and cyclic prefix. HSDPA was more robust in Doppler shift fading because of its shorter TTI. WiBro provides better overall performance in air-link comparing with HSDPA. HSDPA performance degradation in multipath channel is similar with experimental results in lxEV-DO.
